So I set up my system with btrfs in the last days and I converted two external drives (from ext4) (mainly game) and run defrag and balance, because it was mentioned in a guide to compress the existing files. Was that a bad idea? Didn't read anything about duplicates.

Do you have MangoHud installed? Last week I couldn't run any proton game on my system until I uninstalled it/ removed the MANGOHUD=1 variable haven't had this problem before, but something broke. Proton and wine were stuck at launching, no error messages/ logs, etc. drove me nuts.

I am on arch and use both KDE+Wayland/X11 on my 3060ti and for me wayland still has lots of visual glitches, some programs flicker, sometimes the plasma bar is frozen, etc., etc.. Gaming is hit or miss. But I can say, the things that do work are a lot smoother than on X11.

My Sony noise cancelling headphones (XM3). I love them and use them every single day. And also my wall mounted pull-up bar.

Got something similar yesterday, but for KDE-Connect from F-Droid. Downloaded the Play Store version instead.

Geht mir genauso.

Pretty much this. And they are still too expensive.
