SUMMARY
I have a panel with "icons-only task manager" that does not extend to cover all the icons at re-.start of plasmashell.

STEPS TO REPRODUCE
1. Create a panel set to:
- position=bottom / alignment=center / width=fit to content
- visibility=auto hide / opacity=translucent / style=floating
2. Add around 10 icons 
3. log out then log in

OBSERVED RESULT
The Panel only covers the right most icon. When entering edit mode the panel adjusts its size to cover all icons.


EXPECTED RESULT
The panel should cover all icons.

I am seeing similar. My second panel is Icon-only task manager and has the following settings:
Position: Bottom
Alignment: Centre
Width: Fit content
Visibility: Always visible
Opacity: Adaptive
Style: Non-floating

On initial log in, the panel is a fraction of the expected width (see first attachment). Bringing up the Panel Configuration without changing any setting resolves the width to the expected size (see second attachment).
Currently running Plasma 6.2.4, Frameworks 6.8.0, and Qt 6.7.3 on Gentoo. Kernel version is 6.6.58-gentoo-dist, graphics platform is Wayland. AMD processor and graphics card.
