Environment:
* QEMU's latest git, although I've seen this in many earlier versions
* -vga cirrus
* Fedora 12 running as a guest (also happens in the moblin snapshot)
When running the gnome shell preview or glx gears, the display is highly corrupted. It looks like a bytes-per-pixel issue since the image appears in three places.
When using the VESA emulation glxgears works just fine, but the bulk of the gnome shell doesn't. (and I'm limited to 800x600 with no acceleration)
Fedora 12 has rpms versioned 7.6.0-8 so I assume it is a git snapshot.
