KDE 4 - Weird skewed colors in qt4 programs after launching gtk programs.


Strange little annoying issue. I've seen this on another similar setup but that problem is significantly more intermittent than mine.

Starting info:
-Dell Inspiron 9400 with ATI Radeon Mobility x1400 using the open source radeon driver (no xorg.conf file)
-Slackware 13.0 with 2.6.29.6-smp generic kernel (also occurs with huge-smp) and KDE 4.2.4
-Installed kde3 and qt3 libraries for earlier versions of Amarok and K3B (which were installed long before this issue began, but I figured I'd include the info anyhoo...)

Problem:
On a fresh boot, I can open as many instances of a Qt4 app as I wish (Dolphin is my main test subject) until I launch at least two gtk applications. At this point, every color on the screen gets horribly skewed, almost looking inverted (not a true inversion though). As soon as I switch back to any gtk application, the colors are back to normal. Switching back to a qt4 app and the colors are whacky again. Wash rinse repeat. Killing the X server and logging back in returns things to normality until I start launching gtk applications....

I'm wanting to lean towards the radeon driver having issues as the other laptop I've seen this happen to also used a similar ATI graphics chip.

I'll attach my xorg log and a picture (later).

Thanks in advance for taking the time to look at this issue!!!

(EDIT: Took Firefox out of the equation as a possible cause as I tried launching a few instances of other gtk apps and had the same result...)

ruben, negative on the desktop effects. Forgot to mention that. I have used them previously but they would cause weird window borders after suspend to ram and had the typical flicker when watching videos so I disabled them.

Okie dokie.... So it appears as though an upgrade to Slackware 13.1 fixed this little issue. Sweeeet.
I'm going to assume it was an issue with kwin, perhaps?

Hope this helps someone...!
Thanks for looking.
