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?
