Every once in awhile we were seeing problems on MacBooks (Intel graphics adapter) where having CamCamX running in the background would cause some strange behaviour in the foreground application. We think we've isolated this problem to the QuickTime 2vuy to ARGB converter that we were using to drive the MixMonitor window. We've changed things around to use OpenGL for that window, and are being a bit less aggressive when it comes to performance. If you experience any strange problems with display updates when CamCamX is running (1.512 going forward), please be sure to ping us with a quick bug report that includes your 1. OSX Version, 2. Mac Model# and 3. Graphics Card make and model.
