Created attachment 131942 [details] Figure 1 SUMMARY Apparently, since Plasma 5.19.90 the icon spacing got worse, being much larger than usual (essentially the size of an icon by now). This wasn't the case in previous versions of Plasma. Resizing the system tray does not help as it appears to be a hard-coded value (isn't this KDE? I should be able to set this spacing...) STEPS TO REPRODUCE 1. Set global scaling to 200% 2. Move the System Tray to the desktop (it should not be under a panel) OBSERVED RESULT See Figure 1. EXPECTED RESULT See Figure 2. SOFTWARE/OS VERSIONS Windows: N/A macOS: N/A Linux/KDE Plasma: Linux linux 5.4.61-rt37-1-rt-lts #1 SMP PREEMPT_RT Sat, 12 Sep 2020 21:01:23 +0000 x86_64 GNU/Linux/5.19.90 (available in About System) KDE Plasma Version: 5.19.90 KDE Frameworks Version: 5.74.0 Qt Version: 5.15.1 ADDITIONAL INFORMATION There may be a chance that this issue is caused because I am using a HiDPI monitor (therefore set scaling to 200%) and I am aware of Plasma's caveats when scaled...

We did slightly increase the spacing by like one pixel for various reasons, but not by as much as you're seeing. Can you test again after doing the following: 1. Run `rm ~/.cache/plasma*; PLASMA_USE_QT_SCALING=1 plasmashell --replace` 2. Set your Plasma theme to the default Breeze theme and then run `rm ~/.cache/plasma*; plasmashell --replace`
> 1. Run `rm ~/.cache/plasma*; PLASMA_USE_QT_SCALING=1 plasmashell --replace` Effectively, doing that fixes the issue (it does make the icons slightly bigger but it's much better). I don't think there is any way to have Plasma use the Qt scaling value at login time though... > 2. Set your Plasma theme to the default Breeze theme and then run `rm ~/.cache/plasma*; plasmashell --replace` Works as well.
Thanks, Yet another example of Bug 426674, then. I wonder why this regressed so severely recently. At least it's fixed now... *** This bug has been marked as a duplicate of bug 426674 ***
Sorry but this issue should not be marked as duplicate, because the bug still persists after clearing the cache again and not using PLASMA_USE_QT_SCALING (which Plasma doesn't set when logging in due to its experimental status).
Oh, I thought the cache clearing was the common denominator, not the use of Qt scaling. Can you confirm that when NOT using Qt scaling, it looks bad even after clearing the cache again and setting the Breeze theme?

Done, confirmed still reproducing under the aforementioned conditions.
Darn. This situation with Qt scaling is intensely frustrating to me. It's used by default on Wayland, but not X11--even though it results in Plasma generally looking much better on X11 when scaled.
Not sure this is fixable in a generic way, sorry. :( *** This bug has been marked as a duplicate of bug 356446 ***
