      Description

      Unhidden by 0.4.15-dev-2771-g6d441f7d65f.

      This never happened before because VGAPnP (formerly VBE) driver was not attached to the GPU because it was not enumerated by PCI driver, see CORE-17600.

      Earlier the problem could have been reproduced only on real hardware, but now it's also reproducible on xemu v0.7.71. It's possible to workaround problem by removing VGAPnP driver from Xbox port build. But there probably should be more correct fix for the actual bug.

      The source of the problem may be missing VGA BIOS in the Xbox. The responsible memory area for it is probably just zeroed out.
