Hi!

With v4.9, if I maximize "nowcast -x" application, I get broken
display (as if someone split the window into rectangles and shuffled
them a bit). Switching virtual desktops either fixes it or breaks it,
depending in how fast I switch. (Yes, strange).

pavel@amd:~$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset
Integrated Graphics Controller (rev 03)
pavel@amd:~$

Recompile, reboot, and graphics is okay.

(On thinkpad x60, I have seen other strange problems, mostly when I maximize
video, but not as easily reproducible).

								Pavel
