OBS - black screen while capturing display - windows

I have a problem with OBS. I'd like to make tutorials how to do programming, teach people basics & show them, for example, how to write neural network in Java (without any ML libraries) but in order to do so, it would be great to show them my presentation about it and other windows, so recording full screen is needed (I know I could keep switching windows but it's faster and easier to display full screen). When I added the source "capture screen" the captured screen is black but audio works. I've tried to solve this problem and I went through many tutorials (like 15 or smth) and nothing has helped. I've also added a new thread in OBS Official Forum but nobody has responded. My OBS version is 25.0.4. Here is what I've tried:
- I ran the program as an administrator
- I have reinstalled it (with deleting all files and settings ~ no leftovers)
- In Nvidia Control Panel in 3D Settings I've selected OBS Studio and changed graphic processor to an integrated graphic (also tried dedicated graphic and global choice - nothing worked)
- In GForce Experience I disabled sharing
- Couple times I've restarted the computer and OBS (after any change I've done)
- I ran the OBS in compatibility mode with Windows 8 (and I've tried Windows build-in troubleshooting option)
- I ran OBS with an integrated graphic from a desktop
What I've discovered is the capturing specific window works perfectly, the problem occurs only with capturing full screen.
I have no idea what to do, please help me.
Here is what I see:
It looks like OBS just "can't see" screen, I use only one screen by the way
Black screen
though single-window capturing works perfectly

Specifications of my computer:
I use a laptop - MSI GF 63 8RC
- Intell Core i5 8300H
- GForce GTX 1050 (actualizations are installed) 4GB VRAM
- Windows 10 Home, 64bit (updated to version 1909)
- 16GB RAM
- FHD Screen (1920x1080)

You will need to change the Graphic for this app to integrated graphic

I had the same problem in the virtual machine And I solved it this way go to virtual machine setting
in display section uncheck Accelerate 3D graphics
The problem was solved and the recording was done correctly.

How Can I Fix Glitchy Images on Google Chrome?

I would like to ask about these images I found to be glitchy on google chrome.
I must confirm that none of these are intentional.
This started since I saw a glitchy image on my google classroom, here are some images I found to be glitchy. I don't seems to find a pattern from them.
Glitchy image on google classroom
How the google classroom image should look like (my friend's perspective)
Broken logos of chrome extensions (fullscreen)
Broken search icon
Broken pdf icon on web.whatsapp.com
It sometimes manages to fix itself though, I successfully took a screenshot of glitchy icons and the normal ones.
Search Icons, both normal and glitchy displayed at the same time
I've tried to delete images cache and even reinstalled chrome, none of them works to fix this problem.
Some information that might help narrow down the problem:
I've recently used this PC with a new SSD (I've used it for about a month now), which contains the chrome itself, and it works properly so far. I don't think this should be a problem with the disk. (please correct me if I'm wrong)
However, on the day this happens, I installed the React Devtool (I've deleted it though) (https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi) and the Redux Devtools (https://chrome.google.com/webstore/detail/redux-devtools/lmhkpmbekcpmknklioeibfkpmmfibljd)
Can this problem be a bug on the chrome itself, or perhaps something related with skia? Should I report this as a problem to Chrome, or is this a problem on my end?
Information about my OS and Google Chrome (I'll provide more if it is required):
OS:
Edition: Windows 10 Pro
Version: 20H2
Installed on: ‎1/‎10/‎2022
OS build: 19042.1526
Experience: Windows Feature Experience Pack 120.2212.4170.0
Chrome:
Version: 98.0.4758.102 (Official Build) (64-bit)
Thanks
EDIT: Fixed, I changed from using GPU 0 to GPU 1 via settings, is this a graphics card compatibility issue?
GPU 0: Intel(R) HD Graphics 530
GPU 1: NVIDIA GeForce GTX 950M
Setting "Choose ANGLE graphics backend" (chrome flag) to "OpenGL" fixed the issue for me.

Low FPS when naming application explorer.exe

I have an Unity application let's call it X it usually runs at about 60 FPS. But when I rename the executable to Explorer (the same as Windows Explorer) my FPS drops to 7-8.
This is a screenshot from the profiler when the app is named X when the FPS is about 60:
This is another screenshot from the profiler with the same app but named explorer.exe when the FPS is about 8:
This is a screenshot of the GPU usage when named X.exe:
The same app named explorer.exe:
I'm can and will rename the app to something else, but I'd like to know what causes this and how I can figure this out on my own.
Things I've tried:
Disabling my AV which is windows defender and restarting with no effect.
Trying to reproduce it on a colleagues PC, with no success.
This makes me things that it might be specific to my machine and that maybe some process is trying to make some API calls on the other Explorer.exe and somehow affects my app.
In case it's relevant
I'm using Unity 2019.3.5f1
It's happening in the built app both debug and release
OS Name: Microsoft Windows 10 Pro
OS Version: 10.0.18362 N/A Build 18362
System Model: Alienware 17 R4
System Type: x64-based PC
Disappointingly the issue was cause by the fact the my windows was using the CPU graphics card instead of the dedicated one when the app was named explorer.exe.
To change this, I had to:
Go to Settings > System > Display > Graphics Settings.
Browse and pick my app.
Select my app from the list.
Select Options.
Select High performance.
Select Save.
Original source
This made my app use dedicated GPU instead of the integrated one.

Windows Forms text grows too big when run on another PC

I've got a VB.Net Windows Form application containing several controls (labels, groupboxes, comboboxes, etc.) This application is deployed to several PCs running Windows 10. There are also Win10 tablets connecting to these PCs via Remote Desktop. The issue is that the text on the form sometimes gets resized and overlaps onto other controls when viewed on the tablet. In other words, the text becomes too big.
I thought this was only happening when using Remote Desktop but today I saw it happen on a PC too. This is the first time this has happened. One difference is that the PC was re-imaged in the field instead of being brought back to the office first. The monitors used between the two locations are different, and I'm suspecting this has something to do with it. I know there are DPI and resolution factors to consider but don't fully understand how to rectify them in this case, or if they're even applicable.
Here's how it looks as designed and running on my dev PC:
And here's how it looks when running on the production PC (sorry for the grainy image):
Of note is that some text doesn't appear to get oversized, for example the "Currently: 6 ft/min". All fonts are Microsoft Sans Serif.
Suggestions?
The answer provided here worked for me by changing the compatibility settings for the executable. Another method is provided here but I haven't had a chance to test it yet.

blank window when installing visual studio on windows 10

I have a Windows 10 64-bit PC (fresh install, not an upgrade).
When I run the setup file (web or offline alike) in order to install Visual Studio (2013 or 2015, Community edition), all I get is a small black rectangle on the screen (which I later found out that this is actually the title of the setup popup window), without the actual window of the installation.
I have tried it also after a reboot, and with various "versions" of the installation files (web, iso, standalone), but it's always the same situation.
What can I do about it? VS is my main development tool and I really need it on this computer as soon as possible.
Similar problem here. Program install ok but display blank screen after launched.
Problem solved when I changed my Nvidia graphics's global 3D setting to integrated graphics.
Right click desktop
Select Nvidia Control Panel
Select Manage 3D Settings
Under preferred graphics processor, select integrated graphics.
Apply.
If you are using a laptop with an external monitor, try unplugging it and using your primary monitor to launch. This worked for me. Laptops often have dual graphics cards and I believe we're hitting some issue with the way the Installer for VS was written (likely WPF)
Once I launced it and started the installation, I could safely plug my monitor in and it kept working properly.
I'm using an AMD GPU, It was a blank white screen but when I hover the mouse over it, I can see the text events
By the way
I went to my AMD Radeon Settings and saw that vs_installershell.exe and vs_setup_bootstrapper.exe were added automatically to the Switchable Graphics list
they were with Not Assigned Option which usually is like High Performace Option
means It would run it with my ATI GPU.
So I clicked on them
Selected Power Saving Option (to work with my Intel GPU)
Which worked and I can see the window of visual studio installer back
after restarting visual studio installer for sure.
whether is your graphics card, just turn on power saving for it.
Had the same issue. Since this topic is not accept any answare, there is one from https://developercommunity.visualstudio.com/content/problem/150888/visual-studio-installer-shows-blank-screen.html
Try to open installer as Admin.
You will probably have blank screen. Do not close it!
Open installer once more.
Hope it help other people with same issue.
the same thing happened to me, i didn't do anything i just waited for it and it started showing it's status, i suggest you close other running programs to avoid conflicts and performance hindering, and try it again.
This seems like a very shoddy issue. I've run into this problem too, and I tested all solutions that I came across online. These all work:
Running the installer as administrator, which is a blank screen. Leave it open and run a second instance of the installer, which will not be blank (doesn't need to be run as administrator the second time.
Changing screen settings so that the laptop screen is not being used.
Downloading the AMD Settings application, and setting vs_installershell.exe to run on powersaving mode. Restart the installer after saving the settings.
Use a default graphics driver instead of the AMD one.
I had the the same problem in my laptop. The temporary solution is: start the installer only without the battery, if installer starts you can connect the cable, it works fine.
I had to run integrated graphics rather than my Nvdia. That solved it for me.
Remember to change it back when programming in OpenGL and DirectX otherwise you may get a list of messages staying that nothing works.
I had the the same problem in my laptop. The work around is, in device management, remove the amd graphics or start the installer only with battery.

Windows 8 - Start screen icon for IE launches desktop version of IE

When I first installed Windows 8 (64 bit, Pro version, with Media Player), the IE icon on the Start screen launched the Metro / Modern / Windows Store / whatever version of IE.
But somewhere along the line, it no longer does so. It launches the traditional IE desktop version.
Any suggestions how to get things back to normal?
Side questions: I haven't done any spelunking on Windows 8. Any tips for the following questions would be appreciated...
What are the relevant file locations for various "Metro" apps (both Microsoft and 3rd party)? I know about C:\Windows\SysWOW64\WinMetadata for .winmd files. C:\Windows\WinStore seems almost useless. What else is worthwhile looking at?
Ditto for registry entries
What's hidden where? I assume that apps have NTFS permissions set so that, even as an Administrator (and with doing a Takeown) I can't even see certain system/app-related things.
Where is the Start Screen located? Suppose I wanted to write a program that lists the Start Screen icons, their captions, etc
And any other internals info of this ilk would be appreciated.
Thanks.
Go to Internet Options, Programs tab and in the Opening Internet Explorer section disable the ckeckbox Open Internet Explorer Tiles on the desktop.
Greetings.
