I have this problem where when I watch videos in fullscreen from youtube, vimeo etc (flash isssue?), the moment the window loses focus (ie clicking a link in a browser on my other monitor) the video pops out of fullscreen. This happens both in Google Chrome and Firefox.
I've had Mint 14 for about a month, and I'm pretty sure the issue has been since install. I've googled for solutions several times, found interesting answers, tried some of their solutions, but nothing has helped (like disabling one version of flash). I'm basically baffled it seems i'm the only one with this problem, but on the other hand, with so many high valued search words, it's kind of hard phrase to google.
Dunno if it helps, but I can scroll webpages or do any kind of hover activity with the mouse. Flash only pops out of fullscreen when its window loses the focus. I installed Minitube and sometimes uses it if I'm watching something specific in the background, but it's not really a practical workaround.
Anyone got any ideas or had/read similar issues?
