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
