Package: plasma-desktop
Version: 4:4.6.5-4
Severity: important

Dear Maintainer,

The problems occurs only sometimes. I was never able to trigger it, however
my wife experience it very often.
When she moves the mouse cursor to the left edge of the screen, when working
in plasma-dekstop, the screen starts to flicker.
Restart of X (e.g. via /etc/init.d/kdm stop; /etc/init.d/kdm start ) doesn't
help.
I attach the output of intel_gpu_dump generated when screen was flickering
(I run "sleep 5; intel_gpu_dump > flicker" on the text console, and then
quickly switched to the X screen)

¡Hola Wojciech!

El 2012-01-27 a las 00:19 +0100, Wojciech Zabołotny escribió:

The affected system uses the following graphics chipset:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
This is a really old bug, and the plasma desktop changed considerably with the release of plasma 5.
Moving the cursor to the top left part of the screen triggered the expose effect by default, so this seems to be related to: https://bugs.kde.org/show_bug.cgi?id=304375 
Fixed in 4.9.1, so I'm closing the issue with the corresponding Debian upload.
Please, reopen only if you can still reproduce it in kde4 (jessie or older), otherwise report a new bug for the plasma 5 versions. 

Happy hacking,
