I run a legacy X application from 1999, which I can't update. Running it on KDE4 (OpenSuse 11.4) in a chroot environment with an old libc it has been working very well until now.
Now that I switched to KDE 4.8 (OpenSuse 12.2), I'm having redraw issues with text windows when they are scrolled. Its usually OK when I click into the scrollbar to scroll a page, but when I drag the slider the text in the windows sometimes (!) gets totally messed up.
Any ideas what I could try ?
