Are you using a fractional scale factor? Does it only happen at 22px size? What about 20 or 24? Is this s regression from Plasma 5.20?

From 20 to 27 px the icons in system tray blurry and global menu text aliased. Only looks fine when set height to 28 px and above. I'm not using any fractional scale factor.

I'm not using any scale factor (1920x1080 resolution on a 24" monitor) At 20px same problem, at 24px looks fine. If of any help: I'm using "Noto Sans 10pt" as system font (image attached)

Ah yes, at this very thin panel height, everything gets squeezed a bit to retain margins. I don't notice this with a HiDPI screen and a 200% scale factor, but I imagine it's visible with a lower DPI screen at 100% scale. Probably the new margins code triggered this at a greater panel thickness than before. Niccolò, would you mind taking a look?

Or, huh, it should. Could you test if it did fix it?
I thought that was just for left panels. Also that commit only went into 5.22. Finally, I can't test because my screen DPI makes this work fine for me with a horizontal panel. :)
!318 fixed the issue for me; both 20px and 22px height look fine
