Recently, since some update to the latest Flash, I’ve been getting a weird issue. If I’m watching a flash video in fullscreen (via firefox) and hit “esc” to leave full screen, about 20-40% of the time it will screw up the monitor’s display of everything. The entire screen gets weird white and colored pixels randomply all over the screen (see the attached picture).
Restarting is the only thing that fixes this. I tried logging out and back in but the issue remains.
It only starting happening in the last week or so (although I don’t watch a ton of videos full screen, so it’s a small sample size) but I believe I did press the button one of the times to undo full screen and it still happened, but not 100% certain. I’ll have to try that again (at the end of the day as it’s not very good for efficiency during the day ) to see what happens. The problem is that it’s not 100% occurrence even with “esc.” It only happens sometimes.
And KDE or Gnome? On KDE, Power Management and Flash full-screen don’t seem to get on, and on my notebook it’s backlight dimming that definitely screws it up with updates to flash-player 10.2.153 and higher. No problem with Gnome PM and later updates, or an 11.4 KDE I kept back on 10.2.152.
I haven’t had any issues staying back on 10.2.152, but am aware that security fixes to flash-player are missing.
I’m using FF4 with 11.3. But the reason I asked if it’s safe is not because it’s 10.1 but because it’s a download from an anonymous source/url (not official from Adobe).
Interesting. I have a desktop but how do I make sure power management is off (as well as backlight dimming)? Although, I don’t think those had anything to do with this.
This is what I have on standard 11.3 (64bit): KDE 4.4.4, Firefox 3.6.16, flash-player (32bit) 10.2.159.1-0.2.1 (upgraded 19/4). Oh yes, and standard kernel Linux 2.6.34.7-0.7-desktop x86_64.
You will find KDE display power management (tick box) under System Settings > Advanced tab > Power Management > Edit Profiles > choose one > Display tab.
It works perfectly switching in and out of full-screen (with display PM enabled).
