http://bugs.freedesktop.org/show_bug.cgi?id=20892 --- Comment #2 from Torsten Evers 2009-04-09 15:21:49 PST --- I can second this bug and reported it already on ML and @freenode in #radeonhd channel. I made a video showing the corruption: http://www.nightwulf.org/radeonhd.avi The corruptions aren't that massive, when using xrender with kwin but they don't disappear completly.

Don't need to do any thing specific - appears randomly. Have not tested radeon enough to comment on whether it happens there - will try radeon shortly. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

Can you narrow down the problem to a particular accel hook? try the following options to selectively disable hooks:

Option "EXANoComposite" Option "EXANoUploadToScreen" Option "EXANoDownloadFromScreen"

I have just tried these options with latest radeonhd driver from git. I have tested with each option alone, with the three options together, and with both EXANoUploadToScreen and EXANoDownloadFromScreen. In all cases, the result is the same as with none of these options: the background corruption is still there (on a side note, EXANoDownloadFromScreen has a major impact on performance). One more thing I have just noticed, enabling KWin 4.2 desktop effects using XRender composition (since OpenGL is not possible yet on R6xx) reduces significantly the background corruption (I've only tested this with none of the three options). But XRender desktop effects have an impact on performances with the radeonhd driver while they run smoothly with the radeon (xf86-video-ati) driver. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org For additional commands, e-mail: radeonhd+help@opensuse.org

I can second that behaviour of radeonhd. None of the options affects the issue this bug report is about but has impacts on performance (of course). Using kwin as a composite manager via xrender reduces the problems which is caused in my opinion simply by an increased rate of desktop upgrades. These are caused by all that fancy shadow and fading effects.

Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component.

Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd

If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.

As said in the original bug report, the radeon driver (which you refer to as xf86-video-ati) was not affected by this issue. I have not used radeonhd for more than 2 years, and it has not seen any commit for more than one year according to its git repository, so WONTFIX is definitively OK for me. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the QA Contact for the bug. _______________________________________________ xorg-team mailing list xorg-team@lists.x.org http://lists.x.org/mailman/listinfo/xorg-team -- To unsubscribe, e-mail: radeonhd+unsubscribe@opensuse.org To contact the owner, e-mail: radeonhd+owner@opensuse.org
