Bug ID: 493891
Summary: When CPU usage and lag is high, Spectacle recordings
are way shorter than they are meant to be
Classification: Applications
Product: Spectacle
Version: 23.08.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: General
Assignee: noaha...@gmail.com
Reporter: e...@horse64.org
CC: k...@david-redondo.de
Target Milestone: ---
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.
