Screenshot of white stripes in KDE with mesa >8
On computers with INTEL video card (Ivy bridge), Ubuntu 12.04.4 (KDE4.8) and
14.04 (KDE4.11.x?) I can see graphical corruption: white stripes, 3D games like
HeroesOfNewerth have graphical corruptions too.
Sometimes it scramble even cursor of mouse.
The problem probably is not in KDE, because Unity has some problems too.
I tried to downgrade the mesa in 12.04 to MESA 8 and it resolved it.
But in Ubuntu 14.04 I cannot do that.
Reproducible: Always
Steps to Reproduce:
1. Install Ubuntu 12.04.4 (with mesa 9) or 14.04 (with mesa 10.1)
2. Install KDE
3. Use KDE and look at white-stripped graphical corruption and in-games
graphical corruption.
Actual Results: You can see white stripes corruption in KDE and strange
rectangular corruption in 3D games.</pre>
