Comment 38 for bug 1072206

This bug is still present for me. (up-to-date 14.04, nvidia-331, gtx 770 4gb)

If I minimize a window and then switch to it with alt-tab, it will come up black *every time*.

However, I found out today that if I disable *just* the un-minimize animation using unity-tweak-tool, the problem goes away. Minimize animation is still on and the windows still turn black during the minimize animation, but when I restore them, they don't come up black.

Perhaps this is due to some broken interaction between the nvidia driver and the way compiz handles texture transformations of windows.
