Description David 2024-12-16 11:00:35 UTC 
SUMMARY
After updating to KDE6, panel sizes are interpreted differently than before for fixed (non-floating) screen-wide panels. It's not possible anymore to have the same panel size with the same icon size, as it will start shrinking icons much earlier.

STEPS TO REPRODUCE
1. Install a KDE version from the 5 series.
2. Set screen resolution to 4k and 175% scaling. Use the icons-only task manager.
3. Configure the panel to use the icons-only task manager, and to have a size of '80px'.
4. Upgrade KDE to version 6 and restart the system.

OBSERVED RESULT
The panel with '80px' is now much bigger. Attempting to resize it to something with the same icon size as before, such as 56px, still results in a much bigger panel, and attempting to shrink it further will shrink the icons to too small sizes.

EXPECTED RESULT
Should allow having relatively small panels with big icons, like it used to do since its inception.

Yep, I'm afraid this was an intentional change, sorry. I'd recommend playing with panel sizes to achieve something similar to what you has before.

Having a panel of the same height results in much smaller icons. Having something with the same icon size results in a much taller panel. It's not possible to find the same kind of sizes.
