Description Wouter Van Hemel 2014-11-26 12:52:52 UTC 
A few hours after boot, the compositor stops redrawing my screen. The whole desktop isn't updated anymore, the image freezes: all windows still show but are not updated anymore, alt-tab and focus shift don't update windows, and switching desktop probably works fine but doesn't update the screen either. Only the mouse pointer changes depending what is under it.

ALT-SHIFT-F12 turns off compositing and brings back full functionality. Toggling compositing back on, the same frozen desktop appears, the state is never reset.

Making a screenshot is probably useless – just imagine staring at your screen without touching your mouse and keyboard.

I have a feeling something in Firefox or its Flash plugin triggers the bug, stealing opengl "focus" or putting it in such a state kwin can't use it anymore. It happens daily for many months, but I haven't found an exact trigger case as I can't get compositing back in a working state easily to test. Problem persists after toggling compositing off and back on.

It could well be related to bug #330986.

Reproducible: Always

Steps to Reproduce:
1. Work with computer
2. Do something unspecified (might be related with direct rendering in Firefox or Flash)
3. Windows don't update anymore

Actual Results:  
Screen is not repainted anymore


Note: kwin version is really 4.11.13 (not listed in options above), the version in Debian unstable.

Comment 2 Martin Flöser 2014-11-26 13:18:53 UTC 
is there some interesting information in dmesg or xorg log at that time? E.g. a notification about a hung GPU?

Since the lanczos filter seems off (not "accurate", but "smooth" scaling) this would be caused by the blur effect.
-> You could disable it and see if the issue persists.

Other things:
> UXA(0): Driver registered support for the following operations:
You should try SNA acceleration, afair UXA is unmaintained.

> Qt Graphics System: native
Please try the raster graphicssystem here (probably better performance) "kcmshell4 kwincompositing"

Last: please attach the output of "glxinfo -l", thanks.
