[Solved] Task Bar Tags don't close on closing apps.

[Silent Observer]

I installed Debian 12.8 KDE a few days ago on my Gigbayte 97 series MB, FX8350 8-core 4.1 GHz, 30 GB RAM, RTx2070 system with 1 TB platter drive, dual 1 TB SSDs, and 256GB SSD; I'm using the nVidia 535 driver and running Wayland via the Debian Wiki page on installing nVidia.. I've finally gotten everything up and running, most recently getting BOINC (Milkyway, Einstein projects) running and installing Skype with an AppImage repackage of the official Snap release. At first, I had BOINC CPU usage set too aggressive, and was thought that was the cause of taskbar entries for open and recently closed programs becoming unresponsive and losing ability to open a terminal from the taskbar pinned icon -- but I've dialed back BOINC to where I had it on Kubuntu 22.04 (for years!) and I'm still seeing the same behavior.

I had been running a Flatpak of BOINC on Kubuntu because when I last reinstalled it, there wasn't a .deb of a then-current version, but this week I was referred to BOINC's dedicated Debian install of a nearly-current version, Boinc Manager 8.0.2.

Given this issue with permanent taskbar icons has popped up since installing BOINC and Skype, the obvious solution might be to uninstall those applications and see if the problem goes away, but I wanted to check whether others have seen this (mis)behavior with Debian KDE?

I dropped back from Wayland to X11 (same hardware, same Debian/KDE, same nVidia 535 driver) and the issue with sticking taskbar icons (which would eventually result in pinned icons becoming inactive as well) seems to be resolved.

This might be why some folks have been saying that Wayland doesn't yet work with the current Stable branch nVidia drivers. I'm fine with that, Wayland has some nice improvements over X11, but I've been using X11 for a long time (since 2011) and I'm okay with riding it a little longer.
