Hi everyone,
It's been several previous releases since I first notice this problem.
Take a look at the following images, pay attention to the marked areas.
Dolphin
Panel
Amarok
Kmail

Fonts are not displayed correctly.
Scrollbars are not displayed correctly.
Many other widgets have some "noise".

I don't know if QT libs have something to do with this issue.

I'm running Kubuntu 9.10 with KDE 4.4.0, using desktop effects, with "radeon" driver (ATI Radeon 9200 SE video card)

Is this a known bug?

Regards,
Leo

If you create a new user, is the problem present there also?

I created a new user, logged in and after changing the resolution from 1024x768(Auto) to 1152x864 the problem appeared. And changing back to 1024x768 didn't fix it.

Does removing ~/.fontconfig, logging out and back in fix the issue?

After removing ~/.fontconfig, logging out and back in, the problem persists.

One thing I didn't mention is that the problem doesn't appear immediately after logging in, it does after some time, minutes.

If you are using Compositing does disabling it have any effect? Also, try using the VESA driver to see if the video driver is causing the issue.

Disabling Compositing had no effect, the problem persists.
BUT, with the VESA driver I've been playing around for half an hour or more trying to make the problem appear and it didn't.

So, I think it is very likely that the radeon driver is causing this.

Do you know where should I report a radeon related bug?

Thanks.

The Radeon bug tracker ( assuming this is the OSS driver ) is found here: https://bugs.freedesktop.org/enter_bug. ... ver/Radeon
