2019-04-24 14:09:26 Paul Natsuo Kishimoto description 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!
