I’m using openSUSE 11.4 Tumbleweed with KDE 4.6. I started using emacs and I wound when I scroll, emacs gui does not refresh the screen properly, and the characters get messy.
Especially the first column (first chars in every lines) does not go away for a while when I scroll.
Apparently xorg-x11-driver-video|7.6-53.56.1 update in update repo fixed this problem.
I had a similar problem with the same openSUSE 11.4, x86_64. Machine: HP ProBook 6550b, Intel Graphics.
This Xorg library is for 32 bits, that fixed the Emacs refreshing problem. Thank you joonpy.
