This is a really weird problem that appeared in the recent version of Chrome.
I have a huge app that loads hundreds of stylesheets (in dev mode). When the page loads, obviously all styles are applied but background images are missing!
If I just do nothing and wait, suddenly the images start loading randomly...
Using dev tools I checked the network tab to see if the images are requested.. but no, just a few of them appear in contrast to the previous version of Chrome.
Does anyone know if any kind of optimization has been added in Chrome that makes images load lazily? Obviously that implementation is buggy and does not consider a page with a lot of stylesheets!
This problem does not affect the app in production, where all the stylesheets are packed and reduced to just ~10.
Tested on Linux and Windows 7
I had a similar problem with our web site on Chrome 27.0.1453.93 and 27.0.1453.94. It turns out that Chrome seemed to think that all of our .gif images were corrupt. They wouldn't render in Chrome but they would render fine in IE, Firefox, and older Chrome versions.
I'm not sure what the underlying issue was, but I opened the images in Photoshop and re-saved them and now it works fine.

Can someone please shed some light or point me in a different direction.
We are using adobe flash that launches an app inside of a JSP. Up until yesterday everything was running fine without any issues. Today when the Flash Object launches you can see the initialize bar where before you hardly seen it.
While working within the app as well all the operations are very slow (not much but a 2 second delay on most of the things is visible).
I have 3 browsers installed on my PC
IE 11 running Flash version 23.0.0.207
Chrome 55.0.2883.87 running Flash version 24.0.0.194
Waterfox 32.0 also running the same Flash version as IE 23.0.0.207
Running the app from all 3 these browsers is slow apart from Waterfox.
I deleted all the caches from the flash settings in control panel and for chrome I used the web interface (http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html).
I cleared all browser caches. We are running McCafee which I disabled.
I had a look at any windows updates that was done recently which I uninstalled.
What could be different between these? What else can be checked to see what is making this app slow in IE and Chrome?
The slowness could be caused by the files not being cached by the browser like they used to be. I would start there. If you reload the page and you're not seeing a 304 "Not Modified" for the swf(s) you're loading them from the server each time where they used to be loaded from the browsers cache.
Here's some more info on the subject: https://developers.google.com/web/fundamentals/performance/optimizing-content-efficiency/http-caching
Both Chrome and IE have developer tools you can load to see the http calls and check the headers and response codes.

When i load my website on IE10/9/8 some images wont load.
and if i reload the page, the previous images loads perfectly, but some other images wont load.
And if i remove the browser cache, and refresh the page, same thing. some images load and other w'ont load. you can also see that problem in the portfolio page
thanks
Have you tried loading the webpage in alternative browsers? I'm loading it in Google Chrome and all the images load perfectly fine. Internet Explorer utilities your graphics card as well as your processor to load images to make it faster, which might be totally irrelevant for this question but perhaps your graphics card/processor is causing you issues?
If it's working in other browsers, then use them as opposed to Internet Explorer. It will be a bug with their browser and it's compatibility with whatever system you're using. It's the worst browser to use in all honesty.
I just began to explore browsers other than IE and I came across the following behaviour:
In IE9, Flash movies (loading external mp4s) are cached so when you go back to the page it loads from the local copy, whereas in other browsers they seem to start downloading the movie again instead of using a cached copy.
Is this correct or am I missing something?
EDIT: I think Chrome also uses caching like IE9. so the question refers to Firefox and Safari only.
LATEST: Ok I have played around with Safari and Chrome and the issue is not to do with the caching. The issue is in flash swf, when I am loading external movies into the same player because I am using LOAD in actionscript it loads from the beginning because of the difference of the MP4 file. whereas using the same clip it uses the cached movie.
Is there a way caching the played movies from actionscript?
I have gone through the horrors of Flash caching files as well, however it was FF and Chrome that gave me the most trouble. Unfortunately, there is no way to control how the browsers cache. That is up to the user of the browser. Through an SWF you can not tell the browser NOT to cache and you can not tell the browser TO cache.
Does that answer your question?
I'm having troubles testing a StageVideo file locally. The HTML file that contains the swf loads perfectly in Chrome & FireFox, but when I go to open it in Internet Explorer 9 nothing happens (it just shows a white screen).
I've added the permissions for the location to the 'Global Security Settings' tab of the Flash settings manager (on the Macromedia website). I've also checked in the IE9 settings to make sure that it allows GPU rendering.
Has anyone encountered anything similar or have any suggestions as to why it might be blocked in IE9?
Thanks in advance.
My gut feeling is that you don't have the latest Flash Player for IE, but do have it for Chrome/FF since they're 2 different versions. The swf probably doesn't even load up because of the Flash Player requirement.
I'm having a strange issue with Chrome.
I'm working on development with a very image heavy website. If I reload a page over and over again, eventually half the images or more will just disappear. (they don't seem to be broken, just not visible).
If I clear my local cache in Chrome and refresh the page, the images return.
Any idea what may be causing this and how to possibly fix?
edit: just to note, it's not just me. Others hav reported the same issue on the website I'm working on. Always Chrome.
Images, which contains "content-length" header randomly disapper, removing this at the server side solves this bug...
(chrome dev team has this issue in "open" state in their bug tracing system)
I've been getting this recently too. I generally use the latest dev channel for Chrome and assumed it was related to that, but even when launching the regular version of Chrome I get the same issue. I've only noticed it for the past 2-3 months though. Hard-refresh does the job, but it's a really odd bug.
