I recently upgraded from 18.10 to 19.04.
What I expected to happen: same performance as before.
What happens instead:
- I experience frequent locks of input lasting from 0.5–5 seconds, during which:
- The mouse cannot be moved or clicked.
- Any pressed key is repeated for the duration of the lock.
Various events seem to trigger the locks:
- Typing this bug report in Google Chrome (locks for 0.5 s every ~20–30 s).
- Changing tabs in Google Chrome (locks for 0.5 s).
- Changing tabs in the Atom editor (locks for 1–5 s).
(I will test without other applications running after filing this bug and comment with more events.)
Accompanying symptoms:
- CPU usage for gnome-shell is high:
- Always around 20%
- Appears to spike to 100% for longer locks (from eyeballing htop open in gnome-terminal)
- The following appear in 'journalctl -f':
Key repeat discarded, Wayland compositor doesn't seem to be processing events fast enough!
