Priority: medium Bug ID: 63732 Assignee: dri-devel@lists.freedesktop.org Summary: [KDE] - display switching problem with kwin_gles and radeon driver. Severity: normal Classification: Unclassified OS: Linux (All) Reporter: flateric@atlas.cz Hardware: Other Status: NEW Version: 9.1 Component: Drivers/DRI/Radeon Product: Mesa
Created attachment 78244 --> https://bugs.freedesktop.org/attachment.cgi?id=78244&action=edit Dualdisplay bug.
Hello,
with radeon driver and mesa in version 9.1.1 I have problem with switching display between notebook and external display in KDE 4.10.2 with kwin_gles compositor in compositing type OpenGL.
Setting dual display (left/right/above) or switching between displays, causes broken screen. Please, check attached screenshot.
Downgrading to mesa version 9.0.2 solve this problem.
With intel GPU/Driver is everything OK.
KDE version 4.10.2 GPU: ATI x1400, driver - radeon Kernel: 3.8.7 mesa version: 9.1.1 ati-dri version: 9.1.1

--- Comment #1 from Alex Deucher agd5f@yahoo.com --- Please attach your xorg log and dmesg output. I suspect this may be related to bug 61182.

--- Comment #2 from Honza Tvrznik flateric@atlas.cz --- I must say that I don't have any problem with kwin (but kwin is too slow for me). This bug is present only when I'am using kwin_gles.
Maybe this bug: https://bugs.freedesktop.org/show_bug.cgi?id=61600 is like this one, but, for intel driver.
Parts of dmesg and full Xorg.0.log attached.

--- Comment #5 from Michel Dänzer michel@daenzer.net --- (In reply to comment #2)
I must say that I don't have any problem with kwin (but kwin is too slow for me).
FWIW, there is no inherent reason why kwin using full OpenGL should be slower than kwin_gles, but there is a kwin bug where it uses MSAA when it shouldn't. Supposedly that's fixed in current current kwin snapshots.
