Steps to reproduce, under Unity 3D with the Nvidia proprietary driver (on my machine, GeForce GT 240):

1. Minimize a window, by any means, mouse or keyboard.

2. Restore it with the Alt-` key. You can Alt-Tab through the window spread, Alt-` just needs to be the last key you hit, to activate the window.

3. Repeat if necessary. It does not happen every time, for me, but generally within three tries.

    * Once you have done this, window will show as blank, in the spread.

    * I think for some similar bugs, the window would be blank in the spread, right after being minimized. Not the case, here.

4. Un-maximize the window, and the content will re-appear.

    * Sometimes, it will reappear under other conditions. I don't have a strict definition for this yet. These operations restored the content with other apps, but not with Firefox:

       Minimize again, then restore with Alt-Tab or the mouse. I was able to repeat this with Totem, just now.

       Switch to another instance of the app, then back. I was able to repeat this with EoG.

I will add more if I find it, but this has been sitting unfiled for a bit, and I think I need to get it started. Thanks.
