[gentoo-user] KDE4 desktops interference

[Andrew Gaydenko]

Say, on desktop 1 I have started konsole with long emerging of something (i.e. 
konsole window is changing continuously). At the same time I have started 
supertuxkart for my son on the desktop 2. The game window has black blinking 
rectangular with the same position and size as the konsole window (canvas 
itself) has. The same "effect" takes place with replacing active konsole with. 
say, firefox download window (progress bar and text are blinking).

It iseems I have some gl tuning to perform. ~amd64 and intel video card are in 
use. Thoughts?

I have the same problem, when running a full-screen game any pop-ups
(like new mail notifications, etc) well cause chaos...

So, I just make sure to close programs that cause pop-ups while
playing my game :) I think it must be related to the KDE4 desktop
effect, because it didn't happen before then.

Hmm, pop-ups do cause chaos, but the problem the OP described (program 
on another desktop causing graphical glitches) does not occur here. 
AMD64 with an ATI Radeon 4870 here.  KDE 4 effects are on.

More simple and more exciting :-) - just have started glxgears and switched a 
desktop - glxgears' canvas is visible on any desktop!!

OK, that's definitely a driver problem.  It seems the driver does not 
support accelerated 3D while compositing ("Desktop Effects") is enabled.
