Then just don't use it?

In plasma 6 it seems like some apps are actually going to have reduced padding so I wouldn't worry.
I mean it's not surprising if theyre not actively trying to troubleshoot their problems. I run Linux on both my desktop and laptop and I never had a perfect experience with either. On my laptop a few years ago I tried installing Ubuntu but my trackpad sensitivity on linux was way too high with no easy way to change it. I also needed fractional scaling and at the time Ubuntu used X11, I found some command on the Ubuntu forums to enable scaling in the settings and it gave me screen tearing. After a few hours of playing around with different commands I gave up and weny back to Windows.
On my desktop I use Nvidia and have two monitors with different refresh rates. That causes a lot of issues and I just have to put up with it.
Edit: I use Arch on both of them now and have found solutions to my problems but especially my laptop issues were very annoying.
it has something called sandboxed google play services. they claim its more secure and private than microg. also in my experience notifications and location is more reliable with it than microg. also you can disable the constant notification for apps like signal and it still works afaik.
GNOME is pretty much alone in offering no option for icons on the desktop. Distros like Ubuntu and PopOS use an extension to hring this functionality back and you can on any GNOME desktop yourself if you need to. Other DEs offer it by default.
Firefox has librewolf for desktop.
