Describe the Bug

A dual monitor setup - one 3440x1440 100hz, the other 1920x1080 60hz. I use the former for streaming sunshine. If the second monitor is active on the client (not streaming sunshine on it), decoding frame rate 100fps, rendering framerate 60fps, loss of frames due to network jitter = 40%. If inactivating the latter monitor on the client, both framerates 100fps and 0% frame loss.
