I had to set animation to "none" in CCSM -> Animations -> Unminimize Animation.
Do they plan to fix this bug?

Title:
[nvidia] Blank windows when you Minimize, then Restore with Alt-`
(Alt-Grave)
Status in NVIDIA Drivers Ubuntu:
New
Status in “compiz” package in Ubuntu:
Confirmed
Bug description:
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 window of the same app, then back. I was
able to repeat this with EoG.

Bug 938658 was also about blank windows when restoring from minimized.
The conditions were a bit different. To help triage this, here are a
couple comments from there -- one by the maintainer, and one from
another user confirming this problem.

@Edward: I suggest that you open another bug report describing
exactly the condition for the remaining issues (quite a lot of noise
in that bug report). I'll then have a look at it and see if it can be
worked for a stable release update :)

In-line with comment #56, I can confirm that the Alt-` (grave
accent) window switch produces a blank window several times in a row,
while Alt-Tab and maximizing by mouse works just fine.
