Strange graphic bug with fonts

Hi there,

every now and then I experience a strange graphic bug with KDE 4.2 that corrupts some of my program labels. Check out the following screenshots:

Shift-Alt-F12 doesn't help. I can only get back to normality by restarting the X-Server. Really annoying that.

Does anybody have any idea, what might cause this?

TIA,
Blackhole

Re: Strange graphic bug with fonts

Thats exactly what was happening to me in kde with my nvidia 6800 card with the 173 driver

until I went to my /etc/X11/xorg.conf and commented out

Option         "PixmapCacheSize" "300000"

Also, kde crashed at startup until i removed
Option         "BackingStore" "True"

Before:                                                             After:

Hm, I do have a nvidia card. It's the "Quadro NVS 110M" on my Latitude D620.
However unfortunately I do not have the line you were posting in my xorg.conf:

Re: Strange graphic bug with fonts

hmm, here is my old xorg.conf: http://1lordanubis.yakkel.com/xorg.conf

I really have no idea... but if I were you I might try trial and error; commenting out these:
    Option         "Xinerama" "0"            <-doubt its that, but I've never used/seen it before
    Option         "UseEdidDpi" "FALSE"
    Option         "DPI" "100x100"
    Option         "Composite" "Enable"

Hm, without Composite now Desktop Effects, right? And without the DPI settings ugly fonts. So I really don't know. The only thing might be the "UseEdidDpi". Does anybody know what this option is doing?

Re: Strange graphic bug with fonts

Well, I tried removing the UseEdidDpi Option, it didn't help though. This bug is driving me nuts. Does anybody have any idea, please?
At this point Linux is unusable for me. If you can't read your screen content, you can't use your computer, can you?
