Created attachment 57158 [details] corruption in the wallpaper (screenshot) When I suspend and resume my laptop (Lenovo T61), there's a small chance I'll see some kind of screen corruption on resume. Example 1: wallpaper. Example 2: some text in the Unity dash. Example 3: unity launcher tooltips. Example 4: corrupt icons in Docky. The corruption doesn't go away as I move windows over it. My uneducated guess is that the texture memory of OpenGL-using programs somehow gets corrupted. The corruption pattern is very interesting. Pairs of adjacent runs of pixels (16 wide) get swapped in some scanlines. I run stable releases Ubuntu as soon as they're upgraded, and I've seen this bug since early 2011. Currently I'm looking at the corruption with the following components running: * X.Org X Server 1.10.4 (Release Date: 2011-08-19) (2:1.10.4-1ubuntu4.2) * /usr/lib/xorg/modules/drivers/intel_drv.so version 2.15.901 * kernel 3.0.0-16-generic #28-Ubuntu SMP Fri Jan 27 17:50:54 UTC 2012 i686 * i915.ko srcversion E4C84F7B61AD45B310C60E1
