Video recording frezze for a second using NvFBC

Describe the bug Sometimes, when I'm recording with OBS, the video (not the audio), gets stopped for some time (about a second), and then continues. When you are recording, you don't see this problem on the screen. I'm not sure if this is a problem of this patch, the driver or OBS.

To Reproduce Steps to reproduce the behavior:

1. Simply record a video with OBS

Expected behavior The recording must be normal
