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</pre>
