SUMMARY

When CPU usage and lag is high, when pressing stop while a Spectacle recording is going on, it will often be cut off way too short by a significant amount like ten seconds or longer. It seems like the recording somehow needs to "catch up", and when pressing stop it doesn't save until the time when I actually pressed stop but rather only to wherever the internal video creation process has caught up to at that point. This seemingly makes it impossible to actually end a screen recording at a predictable point without neither tons of nothing at the end nor a significant action cut off.

STEPS TO REPRODUCE

1. Cause a lot of CPU and GPU load that is ongoing
2. Start spectacle recording
3. Do some actions on screen, then stop right after the last action

OBSERVED RESULT

The video is laggy, which is expected. The video is also way shorter and cuts off a lot of what you did on screen before pressing stop, which isn't expected.

EXPECTED RESULT

The video isn't cut short even when the system was experiencing lag.
