Created attachment 111090 [details] Perf report on the left, and the pseudo-joystick on the right, as seen by KDE Using Plasma on wayland (doesn't append on X), there are a lot of system calls (seen as kworker activity) (see: screenshot and perf report) that are made and lead to a constant 60% use on one of the cpus (=30% total CPU usage) to a joystick that doesn't exist (similar to https://bugs.kde.org/show_bug.cgi?id=336907 except for the unusual CPU usage part). Reproductible all the time, because constant. Using arch linux with KDE unstable repos, and up to date. Not sure if this is the right product, feel free to move it to the right place. Package versions: -linux-ck 4.15.6-1 -kwayland 5.43.0.1 -kwayland integration 5.12.2-1 -plasma-wayland-session 5.12.2-1

Created attachment 111091 [details] (for real this time) Perf report on the left, and the pseudo-joystick on the right, as seen by KDE Had to take the screen from X (didn't find a way to do it in wayland), but the perf report is of course the one from wayland
The device is created by the Linux kernel or used. We cannot do anything about incorrectly delivered devices.
Created attachment 111092 [details] attachment-7511-0.html I dont get why it would happend on plasma/wayland only...
