We tried to do pair programming (screensharing no video).
It worked quite nicely but for 2 things:
1-blocky screen every time we changed file (could be related to the other bug on cam)
2-high CPU usage. On my i7 4Mhz linux it was using 22% instead of 14% that Slack screen sharing is using. On my colleague old i5 Mac, it tooks 80% and made the machine unusable, regardless of whose the video sharing was.
