I found out that this is not a Plasma bug because it also manifests on Mint with Cinnamon. It can be fixed by setting kernel parameter btusb.enable_autosuspend=0 . See https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1801642 for more info. |
Created attachment 132353 [details] mouse jumps SUMMARY I use Bluetooth mouse. When I leave it inactive for about 3 seconds and then move it, cursor doesn't update its position for a short time (maybe 100 ms) and then jumps into new position. It looks like mouse gets disconnected after 3 seconds and then it needs to reconnect, when I move the mouse. This issue was not present with 5.19. STEPS TO REPRODUCE 1. Connect bluetooth mouse 2. Wait for cca 3 seconds 3. Move mouse OBSERVED RESULT Mouse cursor jumps. EXPECTED RESULT Curso movement should be immediate and fluid SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro Testing KDE Plasma Version: 5.20.0 KDE Frameworks Version: 5.75.0 Qt Version: 5.15.1
