Panorama VESA driver

1280x800 x 16M - OK
1440x900 x 65535 - OK
1440x900 x 16M - trash on the screen, you can see part of the screen, damaged

• widescreen activator for intel doesn't help

LightElf?:

Let's check the source code of Panorama VESA,
what happens during copy of data? Maybe xResolution*Bpp is used instead of ScanLineBytes?. Or BIOS is using 24bpp instead of 32bpp

If disable shadow buffer:
the problem is not fixed. the same effect on the screen.

This ticket is a duplicate of #5.

It would be nice if I could fix this problem. If it was a Panorama problem I could fix it, but is isn't so I can't. The BIOS does not properly switch to 1440x900x32bbp when told to do so. You cannot use that mode on that system. The only other option would be to add some code into Panorama to remove the 1440x900x32bpp entry from the table so you can't select it.
