LOLA: Low Latency Audio Visual Streaming System
F.7 Video Artifacts if LOCAL and REMOTE video windows overlay on screen.
If the LOCAL and the REMOTE video Windows overlay one to the other on the screen, the
foreground window may display some artifacts in the area where the background window is laying behind it.
This issue is still under investigation. Thus avoid to have partially overlapping LOCAL and REMOTE
windows on the the screen while using LOLA. The issue is not present if one of the windows uses the full
area of the screen.
Fig 21: note the artifact in the area where the 2 windows overlap
(in this case a different color rendering, but it can also be a partially late frame area).
