Compositor (wild guess) snow flakes when resizing konsole
I'm guessing this has nothing to do with drivers but when I tile konsole the whole screen snowflakes. Nvidia 270.41.06_64 KDE 4.6.2 Xserv 1.10.1.
Nvidia's problem is a softlock that occurs sometimes this snow happens and X freezes over. The snow then evolves into major graphics corruption.
I get this in dmesg:
NVRM: Xid (0000:01:00): 13, 0001 00000000 00008397 000015e0 00000000 00000100
nothing in any other log
