Hi Greg,
I've been playing around with this to see if I can reproduce the
behavior you describe, and I think I've seen it in certain situations
where there are OMGraphics being projected in pixel space very far
away from the window space. I haven't had a chance to really take a
look at it yet past that.
Do you notice if it occurs when certain layers are being used?
There is an Environment flag that might help, setting
Environment.doingXWindowsWorkaround == true, if that's not already
being set.
