X or wayland?

Comment 2 Aaron Miller 2022-03-15 00:43:18 UTC

This is X. I am unable to test Wayland anytime soon.

Comment 3 Sander Lindeman 2022-03-17 10:39:40 UTC

I'm having the same issue on X11. I've tried using Wayland but I could not reproduce the issue there.

It does not seem to be suspend-related. If I turn off and on the bluetooth on my mouse, I get the same result: scroll direction is reverted back. Also when I switch my mouse from bluetooth to usb-dongle the same happens.

I think you are correct, and I was mistaken. I have a USB wireless mouse, not Bluetooth, and I can reproduce the scrolling problem by unplugging and plugging back in the USB dongle.

I will change the bug title accordingly.

A bug report about this has made it to the 15-minute bug initiative: https://bugs.kde.org/show_bug.cgi?id=435113
So hopefully this will be addressed soon!
