I've run SCIrun exclusively with HD3300 ATI on Linux. Not a single
time I had such issues. It might be platform-driver specific.
So don't be so quick to blame it on ATI ;) ATI is better than NVIDIA
in many respects, drivers not one of them :P

Hi Chris,

This is a known problem with AMD/ATI cards. There is a warning on the SCIRun
site under the Specifications and Mac OS X tabs, and now in the FAQ. We're
not seeing this problem with NVIDIA cards. We're testing the latest OS
updates and XQuartz releases, but don't currently have a solution for SCIRun
4.

I just installed SCIRun 4.6 on a new Mac Pro running OSX 10.8.4. This system
has two monitors, one connected through the DVI port and one connected
through a Mini-DVI to DVI adapter. The video card is a ATI Radeon HD 5770.

As soon as I start SCIRun and open a render window (ViewScene) I see a white
screen flicker on one screen and the other screen becomes scrambled (see
below). It appears that only a reboot can get things back to normal once
this happens. Has anyone else observed this behavior or have ideas about how
to solve it?

Thanks,
Chris
