I have a 4MB Diamond Stealth64 Video 3000 which I have finally managed
to get working with XFree86, except for a screen and font corruption
problem: the lower portions of the screen get corrupted by vertical
lines of dots, while the fonts used in xterm etc. are also corrupted.
The corruption is constant for a given letter in a given font - i.e. the
dots corrupting 's' in an xterm are always the same (except that more
appear with use).
Both problems get worse during use of X - in particular, if a command
generating a lot of text output is used in xterm, both problems get much
What is happening, and can I fix it?
My best guess is that I am getting interference between memory on the
card where fonts are stored and the memory for the screen itself.
