Blit Data Corruption
During a blit, the last QWord of data on a scan line will substitute the second to last QWord of data
when clipping is enabled. This condition takes place when the last QWord of data is not full of
pixel data.
24bpp, up to the last 2 pixels can be corrupted, for 16bpp, up to the last 3 pixels can be corrupted
and for 8bpp up to the last 7 pixels can be corrupted. This can result in up to 7 pixels being
corrupted at the end of a scan line.

Flat Panel Pixel Doubling Mode
The flat panel display engine change cannot handle mode switches into a flat panel pixel doubling
mode without being disabled first.
write to this bit is detected, the flat panel engine must be disabled and restarted. This results in
proper DCLK/FCLKOUT synchronization. Windows does not allow applications to write to
registers that set pixel doubling modes. Legacy DOS applications that attempt to change the video
mode to pixel doubling mode can still cause this issue to appear.
BIOS workaround, No planned stepping fix.
Anisotropic Texture Mapping
Anisotropic logic with multiple textures uses the incorrect textel under certain conditions with
color or chroma keying enabled. This issue takes place during texturing in the case of a multi-
texture polygon, when the first texture is anisotropic and the second is not, and the first texture has
color or chroma key on. In this case the kill bit for the last pixel of a 4X4 pixel span for the first
texture can get lost and the pixel is displayed when it should not. This problem requires a unique
set of conditions to appear. First, anisotropic logic must be turned on, which requires more video
processing in the video hardware. Second, multiple textures must be applied to a single polygon.
No planned fix.
