Hi there!
I'm not sure if this is the same bug I've been having for years, but
here goes.
Currently running Ubuntu 14.04 with Nvidia drivers 343.36.
After I come back from suspend, anything that seems to rely on GPU
acceleration is garbled.
In blender all the textures are replaced with colourfu

Now it works, but when i resume my PC i see two screens in one monitor.
I think that is a problem of my PC, because when i open Monitor in
System Settings i find two monitors connected, but indeed there is only
one monitor connected. I opened a new bug here:

I am also still getting some occasional corruption (on KDE) with the
331.38-0ubuntu5 drivers when resuming. I don't get freezes anymore, but
what I do see is windows that were open before suspending becoming
glitched (see attached screenshot) but those do not occur every time

Apparently, things are better with the patch, however the launcher still
shows corruption, which goes away if you refresh the screen.
I suspect that Unity's launcher is simply not being redrawn on resume.
