Normal size

SUMMARY
When setting the panel icon spacing to large, the arrow becomes way too big.

STEPS TO REPRODUCE
1. Place a system tray widget on a panel (height of 50, for reference)
2. Set panel icon size to small and panel icon spacing to large

OBSERVED RESULT
Notice the comically large arrow.

EXPECTED RESULT
The arrow should not change size, it is scaled correctly on normal spacing.

I'm not able reproduce this on Fedora 42 with 
I'm also not able to reproduce this in git-master Plasma. The arrow icon stays the same size with any icon spacing in the system tray.

Out of curiosity, are you using one of the Breeze icon sets or another one?
Comment 3 Mathis Paquet 2025-07-08 02:26:43 UTC
I am using the Breeze icons, yes. Perhaps this is affected by panel size and/or DPI and scaling?
Comment 4 TraceyC 2025-07-08 15:46:04 UTC
I'm not able to reproduce this on a Laptop, built-in display 3840 x 2400 @ 150%
2 external monitors 3440 x 1440 @100 %
I tried different panel sizes in the 40s and 50s

What is the display resolution and scaling on the display where you see the bug?
Also, do you see the same bug on a new user?
Comment 5 Mathis Paquet 2025-07-08 17:45:14 UTC
I have no idea how to reproduce, I cloned my panel to the top, deleted the original and put the cloned one in the original's position, now it's not doing it anymore.

I just found it has to do with Panel Colorizer
