SUMMARY When starting kwin wayland, after a while, the window list freezes and doesn't show any changes for my opened programs. Also, when I close al programs and click on the symbol of one program in the window list, all closed programs that are still visible in the frozen window list are opened up again. *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. start plasma wayland 2. open a bunch of programs (in my case kontact, firefox, system monitor and dolphin) 3. do things until the window list freezes (in my case, this happened pretty fast) 4. close all programs 5. click on the symbol of kontact (or any other program on the window list), which is still visible as being open OBSERVED RESULT All programs that still have icons on the window list get reopened EXPECTED RESULT No freeze, no reopening. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.27 KDE Plasma Version: 5.27.7 KDE Frameworks Version: 5.108.0 Qt Version: 5.15.10 Kernel Version: 6.2.0-32-generic (64-bit) Graphics Platform: Wayland Processors: 6 × AMD Ryzen 5 4500U with Radeon Graphics Memory: 15.0 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: Acer Product Name: Aspire A515-44G System Version: V1.12 Additional Info: It is the symbol only window list, not the standard one.
The same thing happens with the standard window list. Oh, and I have put my panel on the left side of the screen, so not standard at the bottom.
Can you confirm that you are using the widget actually named "Window list"? Or is it named "Task manager" or "Icons-Only Task Manager?" Does the rest of the panel contents freeze too--such as the Digital Clock or the System Tray?
Well, in German it is called "Fensterleiste nur mit Symbolen", but in English it might be called "Icons-only Task Manager"... ;-) The list somehow half-freezes. Animations and icon changes freeze (like the spinning wheel on kontact right now doesn't go away, and dolphin isnt shown as being opened). The clock does not show time updates, but I can still click it and it will open the mini calendar. Opening the system tray works, but without animations. I tried doing a video with spectacle, but then my system becomes unresponsive, and the cpu usage goes to 100%, so I can't do it unfortunately.
Some more weird behavior: - Programs opened after the freeze do not show up in the list, nor do they show up when doing ALT-TAB, but they show up in system monitor.
Thanks. The symptoms seem to be the same as in Bug 469016, but that one says it's specific to NVIDIA GPUs. Maybe there's a codepath here that affects AMD GPUs.

Well, does this bug also happen only if "Show small window previews when hovering over Tasks" is enabled in the Icons-only Task Manager Settings? That's the main takeaway from the other bug
Did you change anything in "plasma renderer" settings? Please share your kdeglobalsrc
which one? I have three kdeglobals: one in ./config/kdedefaults, one in ./config, and one in ./kde/share/config... The one in ./config has been changed a couple of minutes ago (probably on login), the other two haven't changed since 2022.
It seems to be a duplicate of Bug 469016. I tried the workarounds mentioned, and they work for me as well (moving the panel around).
Pretty sure it's aduplicate. I disbaled windows previews and it now seems to work. *** This bug has been marked as a duplicate of bug 469016 ***
