SUMMARY

Kickoff stretches upwards after switching between alternative widgets on X11

I was unable to reproduce the problem on Wayland.

Also, I'm not 100% sure, but it seems this problem has been occurring since Plasma 6.5.

STEPS TO REPRODUCE

1. Make sure that the X11 session is running instead of Wayland
2. Switch the widget to an alternative one
3. Switch the widget back to kickoff

OBSERVED RESULT

The kickoff widget starts to stretch upwards.

EXPECTED RESULT

The kickoff widget should not stretch by itself.

Strange.. I can easily reproduce Neon Testing on a fresh image (neon-testing-20260127-0431.iso) right in Live mode (even without installing the system). Of course, by re-entering the live session in X11, because default one is Wayland. Inside the qemu-kvm VM (virtmanager).
