Description Lamarque V. Souza 2010-09-11 21:07:57 UTC

Hi, I am facing a lot of flickering in my screen since I have upgraded to
xf86-video-ati-6.13.1 today and using composite enabled. Downgrading to
xf86-video-ati-6.13.0 solved the problem.

With xf86-video-ati-6.13.1 kwin 4.5.1 disables the 3D effects at login, when I
press Shift+Alt+F12 kwin enables them but the flickering starts, specially when
I click on Kopete's systray icon to show/hide its main window. With
xf86-video-ati-6.13.0 kwin enables the 3D effects at login and there is no
flickering. Kwin has some tests that automatically disables 3D effects if there
is something wrong, which clearly is the case.

My card is a ATI HD4570 (M92, pci id 1002:9553). Relevant ebuilds I use:
kernel 2.6.35.4
xorg-server-1.8.2
mesa-7.8.2
libdrm-2.4.20-r1
radeon-ucode-20100408

Reproducible: Always

Steps to Reproduce:
1. Open a KDE 4.5.1 session.
2. Enable 3D effects.
3. Click on Kopete's systray icon. It happens in other situations but this one is certain to trig the problem.

Actual Results:  
The screen flicker.

Expected Results:  
The screen should not flicker.

Hi,

I have some flickering issues as well, but I have Intel (GMA950) on Lenovo R400. I suspect it is some newer versions of drivers, xorg or intel. 

There is a wide array of visual "effects" people refer to as "flickering". Could you post a video of your screen?

My screen looks like this: http://www.youtube.com/watch?v=LC0-HU6XeQk

Thanks.

Looks more like an x11 problem...

This was probably hardware issue. Lenovo fixed it by LCD exchange (but introduced another screen problem... whatever...).

Hopefully fixed long ago. If not, open a bug upstream https://bugs.freedesktop.org/enter_bug.cgi?product=xorg&component=Driver/Radeon
