Occasional jitter

Often ALVR appears jittery when moving the head horizontally. It's probably not the video stream because the oculus universal menu also appears jittery (with ALVR stream in the background). The same thing happens to a lesser degree with VD.
This could be caused by unoptimized code. One of the causes could be the webview that gets rendered constantly even when not shown.
This could also be caused by uneven video encoding/decoding times across frames. A workaround is implementing the latency minimization/regulation system. This system increases (frame queue) latency until the number of missed deadlines per hour (that cause jitter) falls below a certain threshold.
