Comment 42 for bug 938658

Cripes!

I am getting blank windows on restore, again.

* It doesn't happen every time, now.

* It's only windows that were maximized, then minimized. So not exactly the same as Fuzzy or Scott report. Which is frustrating! :)

* It has only happened when switching back to minimized windows with the keyboard. I haven't been able to reproduce it, when clicking on the launcher, yet. Which is different that what we were seeing before. It has happened with Alt-Tab, and Alt-Grave (key above Tab). Neither one does it every time. But keyboard, not mouse, is only distinctive pattern I can see.

The most recent package that's changed is compiz, to version 0.9.7.6-0ubuntu2. I have no idea if that upgrade was a regression, or it just strikes very sporadically. I'll try to downgrade later, to test.

Shayne, or anyone else - if you want to test some more, try:

  maximize->minimize
  then flip back and forth with Alt-Tab and Alt-Grave a lot

Of course, this is probably what you're doing with your windows, anyway. I can often see it within three tries. But, again, not every time.

I don't have much idea what to think at this point. (I can work around this, but it seems a shame to release this way.) I hope someone has more clue. Or that I get a lot smarter very fast. :-/
