Created attachment 184472 [details] The described "ghosting" of the task manager SUMMARY After closing a window that was not pinned in task manager, it doesn't readjust its size and leaves a white "ghost" space. After hovering over the space it correctly updates the task bar. STEPS TO REPRODUCE 1. Open a window not pinned to the task manager (this will resize the manager to fit the extra icon) 2. Close that window OBSERVED RESULT There will be a ghost space where the icon once was, and the task manager won't refresh until you hover over it EXPECTED RESULT It should automatically update, not just when you hover over it SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 42 (KDE edition), Wayland KDE Plasma Version: 6.4.4 KDE Frameworks Version: 6.17.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION This happens when I use breeze theme (dark if that matters), and a new theme I installed to see if it was a breeze issue.

Let me guess: you have an NVIDIA GPU, right?
(In reply to Nate Graham from comment #5) > Let me guess: you have an NVIDIA GPU, right? Yes I should have said, sorry. nvidia-smi (NVIDIA-SMI 575.64.05 Driver Version: 575.64.05 CUDA Version: 12.9) But this only happened recently though.
I had a feeling, because this is a semi-known NVIDIA driver issue, unfortunately. I say "semi-known" because it's known to KDE developers, but I don't know if it's known to NVIDIA developers yet. Please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux. It would be helpful to the NVIDIA developers if you could run `nvidia-bug-report.sh` and attach the resulting file in your report. Thanks a lot!
Thanks, Ill send a bug report
