Hi!
Starting XFree86 4.4.99.903 using the s3 driver at mode 1024x768 8bpp I see the following screen:
0 303 1023
| | |
0 ---BBBBBBBB----------------------+
BBBBBBBB |
BBBBBBBB |
BBBBBBBB GOOD AREA |
BBBBBBBB |
BBBBBBBB |
767--BBBBBBBB----------------------+
where B means that black pixels are displayed always.
I don't know what is the problem exactly but the attached patch removes this bug. (May cause new ones, too...)
