So when i edit videos and videos only the video and audio becomes very very choppy and will lad a lot. This hasn't happened to me before, only after the newest update. And when i tried to dock my media selector it said that the resolution was to high so I changed it to 1200x768 ( the minimum is 1200x700) and the audio stopped lagging but the video didn't. And when i export it's not laggy and when i recorded it it wasn't lagging. Help?
