[Bug 563366] Re: screen corruption when DefaultDepth = 16

 

Still current on 10.10
Only chrome (Both chrome and chromium) and evince seem to be effected for me. An X restart solves the issue. It happens about once every 2 weeks with daily use.

I will try to get a screen-shot next time.

The only log entry that looks bad is from Xorg.log:
