Created attachment 183623 [details] The bug appearing here, notice at the right of the panel SUMMARY STEPS TO REPRODUCE 1. Set panel to "fit content" 2. Open a window from anywhere but the panel 3. Close the window OBSERVED RESULT Panel icons squish to the side but a weird outline is left until you move the mouse over the panel EXPECTED RESULT The panel should resize normally without the icons squishing and an empty part appearing. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 42 KDE Plasma Version: 6.4.3 KDE Frameworks Version: 6.16.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION I initially thought it was due to transparency but after checking it isnt. I am on nvidia with the proprietary rpmfusion drivers (rtx 2060)
Can you confirm if this is X11 or wayland. (and comment on that tooltip bug too)

I'm not able to replicate this on Plasma git-master or 6.4.3 with a panel configured the same way. I know I had seen this in the past on my system. KDE Frameworks Version: 6.16.0 Qt Version: 6.9.1 The git-master system has an integrated AMD GPU The 6.4.3 system has an NVIDIA GPU with the proprietary drivers What size is the panel? I tested with 42, 48 and 50. Some bugs in the past only presented with a specific panel size.
