X11/XRender corruption
Adding/deleting text in Konsole or minimizing a window is a pain in the ass
with the Raster backend. X11/XRender backend is fast but has graphical
glitches.
Linux 3.12 (drm-next merged on top of 3.11.0) but I also tried 3.11.
xorg-server 1.14.2.902
mesa git
libdrm git
xf86-video-ati git
glamor git but I also tried 0.5
llvm git
clang git
KDE 4.11.1
Gentoo
I attached a screenshot of the X11/XRender corruption.</pre>
