Fullscreen Flash locks up when you maximize an MDIWindow in Chrome #1685

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Open the Flash client in Chrome
2. Press F11 or make the browser full screen
3. Maximize an MDIWindow
4. The screen locks up and can't be interacted with

I can only seem to reproduce the problem in single monitor setups. On my 2 
monitor workstation the problem doesn't occur.

I have a server that is running an older version of BBB (build 4283-2013-07-15) 
and I can't reproduce the issue on that server so it seems like the issue arose 
at some point between then and now.

I have finally narrowed down down the cause to three commits. 
https://github.com/bigbluebutton/bigbluebutton/compare/c350b6c...d1ee41a . Two 
of the commits are related to ruby recording files and are inconsequential, but 
somewhere in one (or more) of the three other commits is the cause of the CPU 
spike. I've looked through the diffs and I can't see anything that sticks out, 
but it's there somewhere.

I'm still not sure what is causing this and the effect of the bug isn't always 
the same. Sometimes it locks up, sometimes it crashes, sometimes it's just 
slow. I installed the latest debug version of Flash (12.0.x) and I got an error 
log that might prove useful.
Error #1502: A script has executed for longer than the default timeout period 
of 15 seconds.

It looks like Flash is getting stuck in an animation and after 15s it cuts and 
then continues execution.

Chrome 36, dev.bigbluebutton.org

I cannot reproduce it when enabling Flash Player remote debug. But in Flash 
Player normal mode we can see it.
