Description pei 2010-02-25 19:49:00 UTC

Version:            (using KDE 4.4.0)
OS:                Linux
Installed from:    openSUSE RPMs

When moving the mouse over an icon, the appearing tooltip (not sure if this is the correct term) sometimes destoys a rectangular area somewhere else on the screen.
When the tooltip disappears, the area behind it gets correctly restored, but the
corrupted region stays broken.

I've got a Matrox G550 card, but never noticed similar issues before (mostly using KDE 3.5).

This is an old, known, X.org server issue: bug 177959 (it also contains a workaround)

Thanks, for some reason I did not find all the duplicates.
I have all effects (including Compositing) disabled in the
desktop settings, but I don't have Composite disabled in
/etc/X11/xorg.conf so far. I'll try if that helps.

Is there a way to disable the tooltips themselves?
Usually they don't display any extra information but tend
to cover menu items which can be very annoying.

As far as I know, there isn't a way to disable Plasma tooltips. Sorry

Comment 4 pei 2010-02-26 18:41:51 UTC

After having worked 1 day with new settings it seems that adding

Section "Extensions"
    Option "Composite" "Disable"
EndSection

to /etc/X11/xorg.con really has helped. Thanks again!
