@Zinglish, I’ve got it running pretty smoothly using a communication that updates on mousemove, since that has to be forwarded to CEF anyways. Sure beats temporarily freezing the render buffer and causing crashes.
Anywho - I’ve got my game’s UI set up on a single CEF overlay, and then a few dynamic spool-ups for 3D uis. If anyone is curious how to do I can explain further.
