I tried to call [qUtils drawVideoBackground] after [qUtils pauseAR], most of the time it works fine but sometimes an exception of `gpus_ReturnNotpermittedKillClient` will be raised.
I am sure I called [self setFramebuffer]; before [qUtils drawVideoBackground];
So my question is, is it legal to drawVideoBackground after AR is paused?
Have you tried taking the snapshot just before calling pauseAR() ?
