Jiminy cricket! Disabling hardware anti-aliasing does get rid of the flickering. Too bad that won't be an acceptable option for us. This has to be an OSG problem since it has gotten worse in OSG 1.2 compared to 1.0. Does anybody know if anti-aliasing setup changed somewhere?
Thanks for the info Brian. Zach -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Brian D.

The higher settings seem to flicker a little worse and there is no problem with antialiasing off. What I do is bring up one app full-screen and the other in windowed mode on top of it. The flicker dissapears while either app is minimized but returns when the windows are restored. Anyway, you may try disabling your hardware anti-aliasing to see if that helps. I've only tried this with OSG 1.0, and I note that CEGUI is used in these apps as well.
