I fetched the output after a reboot, as requested. As for KDE, I found an open bug report on this issue (#478797), but it’s been sitting there for almost two years without a fix. If reporting to KDE actually worked, this should’ve been resolved by now. I also found a similar case in the Garuda forums (this post), so it’s definitely not just me facing this.
I originally used the <details> tag just to keep the post cleaner, but I see now that full inline output is preferred. My bad on that. I’ll try X11 and report back if anything changes.
Also, not to be rude, but I really think this issue is worth looking into. Just because one user (me) reports it doesn’t mean it should be left off the fix list, especially when it’s been affecting people for so long.
Just to clarify, I’m not putting this on the Garuda devs, I get that priorities are different. I was just hoping for some workarounds, like the X11 suggestion you mentioned, which I’ll try now : -)
