  Curious, sorry for overlooking PRIME systems in my testing. Since the QtQuick window would be redirected, MaxFramesAllowed=1 should have the effect of forcing glxSwapBuffers to wait until rendering for the previous frame has completed and the back buffer contents have been copied to the front buffer. I'm taking a look into this internally as well, having access to a debug NVIDIA driver might provide some more insight into what's going wrong. Will update with any progress, hopefully we can avoid having to revert the fix.
