Hi,

with recent xserver a lot of people observe a graphics corruption with Cirrus Logic graphics. Especially
in Virtual Machines (easy to test with ubuntu 12.04.3 LTS 64-bit). I am not 100% sure if this is an
emulation problem.

Who can help with debugging? And who eventually has a hardware Cirrus Logic Graphic Card with GD5446
and could verify if the corruption also happens on bare hardware.

The corruption looks as if 3 Byte per Pixel data was copied on a 4 byte per pixel surface.

Thanks,
Peter
