Description Frederik Himpe 2009-04-06 05:43:33 UTC 
When using the cirrus_alpine driver in a KVM 85 (qemu) virtual machine, images are often shown corrupted. It seems that especially KDE is very susceptible to this problem: the problem can be easily seen on most web sites with images with Konqueror.

In the virtual machine Linux 2.6.29, xserver 1.6.0, cirrus driver 1.2.1, Mandriva Linux Cooker.

The host machine is also running Mandriva Linux Cooker (kernel 2.6.29), xserver 1.6.0 and Intel driver.
