Plasma 6 Bugs
If you encounter a bug, proceed to https://bugs.kde.org, check whether it has been reported.
If it hasn't, report it yourself.
PLEASE THINK CAREFULLY BEFORE POSTING HERE.
Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.
I have several Wacom tablets, including a ET-0405-U that has a stylus and mouse with a scroll wheel. The latest Ubuntu doesn't work with the scroll wheel.
Support of these kind of devices on Wayland is still a bit of hit and miss and WiP AFAIK. I have two devices: a cheapo Wacom Intuos something that didn't work at all a month ago, but now works out of the box, and an XP Pen tablet that is recognised, but I can't configure the drawing area.
I guess what I am saying is "patience". Things are improving every day, but not all devices are totally supported yet.
