When working with 2.42RC1 in non-windowed mode (without using -w as parameter), use ALT+TAB to switch to another window (in my case a fill-size firefox). When ALT+Tabbing back to Blender, the GUI is not redrawn completely but a lot of the screen is black. Strange thing is, sometimes it works alright, sometimes it doesn't. If I repeat the procedure about 10 times, there is always at least one instance where it doesn't work right.
To reproduce, use file from bug #4464 and start ALT+Tabbing... ;)
Found in Blender 2.42RC1
System: OpenSuSE 10.0, Geforce 6600, Driver Version 1.0.8756, KDE 3.4

Hi ton,
thanks for the quick reply. I tried the changes suggested in the Linux FAQ (including the buffer flip) and they do not seem to make any difference (for both #4465 and #4464). I rechecked with my Blender 2.41 dynamic install everything works fine (same system, same scene, same kde session, same xorg.conf settings), but with Blender 2.42RC1 dynamic the update problems occures on a regular basis (I can reproduce them every blender session, although it might take a few times of tabbing in and out of Blender)... speaking of which, can't remember when I had the last update related problems using blender. Must have been ages ago... ;)

P.S.: I just took a closer look at a screenshot of the problem. One time, some of the Blender views are drawn correctly (top and side view), the 3d view draws part of the selected object and the preferences/button views aren't drawn at all. Another time, pretty much everything is black except for the 3d cursor...
I also noticed the update is done correctly as soon as I just move the cursor over the boundary of the view into another view (for example from the camera view to my top view window). Attached you'll find a screenshot... looks pretty weird to me...

Did you try the RC2?
Unfortunately a last fix I did didnt make it in this RC2 build...

Didn't know an RC2 was out already, at least there is no binary in the download directory...
I just checked out blender from the CVS, installed what seemed to be about a dozen missing libraries (ok, honestly it was just about three :) ) ... still no improvement. I will try to fiddle with the xorg.conf tomorrow, maybe some weird option beside the NoFlip will have an effect...
By the way, here is my xorg.conf. Perhaps you notice anything problematic (should be pretty standard except for the changes applied from the Linux FAQ):
