Summary: qt applications do not scroll properly with compiz-
fusion and nvidia closed source driver
Product: kdelibs
Version: unspecified
Platform: Debian testing
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: qt
AssignedTo: kdelibs-bugs kde org
ReportedBy: pisano85 gmail com
Version: (using KDE 3.5.8)
Installed from: Debian testing/unstable Packages
OS: Linux
In qt 3.* applications (seen in Konqueror and Kate) scrolling the window has the effect that a part of the previous portion of the screen doesn't scroll until I force a refresh clicking the screen or move the window etc.
Sometimes even the icons on the desktop or in Konqueror come out "half rendered"
To reproduce the problem all I have to do is trying some web browsing... really annoying!
Iceweasel, Amule, Ekiga, Gimp and all the gtk apps I use don't suffer this problem, so I guess it's a qt-nvidia-compiz issue...
You have my Kde version, my distro is Debian lenny, the version of my Nvidia driver is 169.09 (but previous versions had the same problem). I suffered this with Compiz from ufficial repos of Debian and Compiz-Fusion from http://download.tuxfamily.org/osrdebian unstable compiz-fusion-git wich I'm actually using.
My xorg.conf is this (there are some commented options I played with, I'm using it as is here and except for the issue all works fine):
