Large window causes monitor to degauss/reset!!

[Jacob Rhoden]

Hey,

I have been using freebsd for quite some time now, I have come across
a machine with a 19" viewmaster, whereby if you open a window
bigger than about 500x500 pixels, the monitor resets and degausses
every 8 seconds until you close the window. Has anyone had this
happen to them? And how did you fix it? (Freebsd 5.2.1, fairly current
XFree86 with fairly current KDE).

Thanks,
Jacob
