Video freezing and grey frames in QGC 4.0.5 when recording

[Boko (Bo Koppel)]

Thanks for tip!
Installed 4.0.8, works better, still frozen frames, but more seldom.
Graphics already latest drivers.
Tweeked openGL settings in Nvidia settings, got even better.
Still froxen frames during recording, but seldom, almost usable…
Processor load around 50% average while recording, seems double of Yours.
