graphics contents (esp. lists) not displayed correctly in different applications

[ksimon]

see attached png file which is a screen shot from KMail. A similar problem also occured in KSysGuard (process list). Sometimes the text is completely unreadable since only a few pixels are shown. I can reproduce this error now, but as soon as I try to take a screen shot, the (KMail) GUI is rebuilt and OK afterwards.

I upgraded to KUbuntu 9.04 on April 24.

Here a screen shot from Kile. Sorry, this bug makes KUbuntu unusable for me.

I should perhaps have added this:

lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

I could solve the problem for myself thanks to http://ubuntuforums.org/showthread.php?p=7151592. No problems with graphics any more.

One more comment here: When I tried several solutions to the above problem, I changed the xorg.conf in a way that prevented the X11-system from starting, so I had to restart Kubuntu in the rescue mode. I got into a root terminal without entering a password. This doesn't seem quite safe.
Another problem that's mentioned somewhere else too: During the distribution update the GRUB entries were not changed, i.e. GRUB still pretends to start Kubuntu 8.04.
