This is mostly a problem with newer ATI cards in connections with the newest OSX.  I had some issues when I upgraded to osx 10.8.  It is working now, but I have an older ATI card( ATI Radeon HD 4850).   You can try different versions of xquartz, both the newest and some previous versions (make sure your machine is running the one you want) which is what I have done in the past.  I'm running v 2.7.4 now.  However, this may not work in your case.

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

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?



All the best,
Petar Petrov
