Occasionally when I scroll horizontally in an app using the magic mouse, the current tab or page I'm scrolling on freezes and thereon in that app, scrolling is completely non-functional.
For example, if I'm using Safari and I scroll horizontally to go back to the previous link, the current tab freezes, stuck in the middle of the animation. If I close the frozen tab, the other tabs work fine, but I can't scroll vertically or horizontally in them. I have to scroll using the scrollbar. No other apps are affected and if I restart the affected application, everything goes back to normal and the mouse scrolling is functional again.
Has anybody else had this issue? Any ideas on how to fix this?
I was running Lion when this issue started. I updated to Mavericks hoping it would be fixed, but no luck. I'm currently running Mavericks GM on an iMac (latest model).
This is an issue after installing Mavericks. Go to System Preferences/General and click on Show scroll bars: Check "Always". Hope this helps.

I use SkiaSharp canvas to draw the main game screen, and then there are various Xamarin.Forms Buttons around the UI. This all works fine on when used directly on iPhone or iPad using a finger. However, when I connect a mouse (e.g., through a MacBook or otherwise), the buttons start working with about 10% chance after mouse-clicking on the SkiaSharp canvas (and not receiving the mouse click events with 90% chance). The SkiaSharp canvas itself works just fine.
If I bring up the iOS app launch menu from the bottom (which probably somehow temporarily exists the mouse navigation on the app), the buttons start working again with the mouse. But if I click the SkiaSharp canvas again with the mouse, the buttons have a high chance of becoming disabled again. If I change to using a finger, all works fine (even if the mouse clicks were not being registered immediately before). However, mouse clicks are not being registered even after touching with a finger, so finger-touching does not reset the issue with the mouse (but bringing up the menu from the bottom does).
We found this bug by testing the iOS game on MacBook Pro (the iOS apps recently came available on the App Store) but the same issue persists also directly with an iPad / mouse combination. It seems to be some sort of an issue between using a mouse (on iPad or on MacBook Pro), SkiaSharp canvas and Xamarin.Forms buttons.
Does anyone know what the root cause of the problem is and what is the workaround?
Not an answer as such, but some more information about reproducing the issue: A simpler repro case may be this small project: https://github.com/jrc14/TraceMatching/ .
Don't worry too much about what it's doing, but note that you're mean to click in the grey Skia canvas in the middle to create 'targets' - and that after you've done that, mouse-clicks are getting lost.
If you run it on a Mac, you'll see that, though the clicks get lost after you've clicked on the Skia canvas, they will start being received again if you click on something else (another app, or the Mac background).
(further edit) - after some noodling around I did find a workaround. If, once you've finished processing the touch action on the SKCanvasView, you reset its EnableTouchEvents property (i.e. set it to false, then back to true again), it seems that the clicks don't get lost any more,
I have the Canvas preview open and auto-refreshing the view that I am working on.
When I click on the pin in the bottom left corner, it fills with blue, giving me the impression that it's been pinned. But, when I navigate to a different view, that view is then previewed and the pin in the bottom left is still highlighted blue.
I'm currently worthing within Xcode 11.5.
I've experienced the same issue on the, as of writing, latest Xcode 12.4. After messing around with it, I've been able to figure it out; the trick is to make sure that at the time of pinning, the live preview is off. Then pin, change previews, and voila.
Due to performance issues I've change our wall scrolling to use native scrolling (overflow-scroll) instead of js scrolling. (The infinite scroll is working)
The performance is somewhat better but here is the weird thing:
In android, when I scroll down, it just doesn't scroll down after some scrolling (scroll back up is working). When I do something like opening and closing the statusbar of the physical/simulator phone, then it is working again.
I guess it something related to the element refresh of the android WebView, any idea?
When I try to edit a storyboard file in Xcode (Version 5.1.1 (5B1008) under OS X 10.9.3) I can only see the vertical scrollbar. Moving around in the horizontal direction between view controllers is not possible. The horizontal bar doesn't show when I hover over it. It only briefly shows when I select past the visible area but it immediately disappears afterwards and I can only scroll by a few pixels at a time this way.
I have tried restarting XCode and the OS but it didn't help. Scrolling was possible before. It stopped working for no apparent reason this morning. I have not updated XCode nor OS X or messed with the system in any way since it was last working. Has anyone encountered this problem before? Do I need to reinstall XCode at this point?
Press Shift + Scroll Mouse this will scroll preview in horizontal
It's a not bug, it's a feature. It wouldn't be a problem if you use the Apple mouse. There is a workaround for a typical 2/3 button mouse, although it would affect all horizontal bars across the system. Just follow System Preferences->General->Show scroll bars, and select Always.
I have been struggling with this as well. The only solution I found is the following:
So there is a mini map for the storyboard that hovers over the right upper-side.
If you can't see it, just click on the "Adjust Editor Options" button and make sure Minimap is selected.
This is the best way to move around just like you are using the scroll bars.
I installed the latest Xcode and Yosemite betas several days ago and have noticed a feature of Yosemite seems to be its not possible (by design or bug?) to click on a a scroll bar and drag.
This was an irritation but now I'm trying to navigate within a storyboard and there's no apparent way of moving around - there's no navigation bars, there's no arrows, pressing arrows on a MacBook keyboard does nothing, its not possible to click within the story board and move it around, there's no zoom/de-zoom button to expand/collape the Storyboard.
I've been scratching my head then getting increasingly irritated, I just can't see any way of repositioning a storyboard with Xcode and thus I can't do a thing at the moment - there are view controllers in my Storyboard not displayed on screen and I just can't get to them!
Moving around the Storyboard works the same way that it has always worked: drag with two fingers on the trackpad or click and drag the scroll bars.
If neither of those are working for you, it's a bug and you need to report it. Also consider reinstalling Yosemite and/or Xcode because I am unable to reproduce this issue.
