On May 19th, 2008, I posted a question to ubuntuforums.com:

---8<---
Strange problem in my Kubuntu 8.04 KDE4 Remix.

I wouldn't post it if that were in "Desktop Effects: ON" mode, since ATI cards are \
not known to work very good with Compositing.

However, the problem is here specifically when I turn Desktop effects OFF.

So, just for short summary:

1. From the very beginning: Desktop Effects: OFF; all the colors Ok;
2. Enabled Desktop Effects (not Compiz, but built-in Kwin's compositing): colors Ok, \
despite some problems with playing video/running GL apps (it's Ok for ATI drivers);

... BUT:
3. since now, every time I _disable_ Desktop effects, some pictures got incorrect \
                colors (probably inverted), such as:
- Wallpaper image;
- Icons (including Files/Folders, App Icons (in menu, in Task bar and in "System \
                tray").
- Windows decorations - for some themes _only_ (e.g., like "Plastic"; Oxigen seems to \
use normal colors... though it's gray theme, basically %)

Everything else seems to be shown correctly. Including all Fonts/Windows contents \
(even images inside browser(e.g. Firefox) look correctly).


General sense, that the problem affects "bitmap surfaces" inside KD4 apps, only. \
Especially Plasmoids.


Any ideas? (actually, tried to google this question up.. seems it's not as common..)

Note: there are some screenshots can be found in that thread ;-)


It was one of very early releases of KDE4, so I didn't fill that bug elsewhere, but \
decided to wait for newer versions.



However, recently, I updated to KDE 4.1 RC 1..

And even made 'rm -r .kde4'..

The broken colors are still here, when I'm turning Desktop Effect Off. 

Another point: I couldn't find this problem among opened bugs, and there is almost \
nothing about similar problem in Google. So, I'm afraid the KDE Devs are simply \
unawared, and the "stable" release is coming soon ;-)


KDE 4.1 RC 1 was installed by these Instructions:

I have ATI X1600XT card, and fglrx proprietary driver from Ubuntu Hardy repos.
