Alex,
I've seen this problem before. You might want to examine your
visual depth, resolution, and cycle rate. Try the following:
% xdpyinfo
which will give you a list of the various visuals available on your
machine as well as the current one. I also assume you want to use 24
bit color depth.
Now try the m64config command under Solaris, but first read the
manpage because this is a tricky command. The color flash is likely
due to the number of cycles that your monitor is refreshing at. Look
for a higher one (75 or 76 cycles).
After that, use the m64config to change your color depth and
resolution.
% m64config -depth 24
% m64config -res 1280x1024x76 (or some resolution that is available to
you)
Now log out of your X session and log back in. Note that this may
affect some of your other applications if you were running in 8-bit
Pseudocolor mode before.
Hope this helps.
Jim
