SUMMARY STEPS TO REPRODUCE 1. Click the volume icon on the taskbar (or the network icon) 2. Observe that the volume widget does not open, the icon becomes underlined like it is selected, but no widget 3. If you did not observe #2, leave your computer running overnight and try again in the morning? It's a bit random and usually fixes when I restart. OBSERVED RESULT Volume widget does not open, the icon becomes underlined like it is selected, but no widget EXPECTED RESULT Volume widget opens SOFTWARE/OS VERSIONS Windows: No macOS: No (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 Kernel Version: 6.16.7-arch1-1 (64 bit) Graphics Platform: Wayland ADDITIONAL INFORMATION This wasn't happening until a recent system update probably within the last couple weeks, and now it happens about once a day or every other day. Running `journalctl --user -f` showed no additional logs while it was happening and clicking the taskbar icons. Restarting plasmashell fixes it, e.g. `killall plasmashell; kstart plasmashell`
Apparently I missed the summary section and I can't edit the post. Here's a summary: Clicking systemtray icons such as volume or network randomly stop opening their respective widgets, instead just showing the outline and the dropdown error changes like normal, but no widget. Once it happens, widgets stop opening until a reboot or plasmashell is restarted.
Do you have an NVIDIA GPU?

Thanks. Looks like the same issue as Bug 480800, or a recurrence of it. That issue had to be fixed in Qt. There may be another change in Qt required if this issue is coming back. :/ Or it could be a regression in the NVIDIA driver itself. Either way, it's an issue somewhere upstream, not in Plasma itself. *** This bug has been marked as a duplicate of bug 480800 ***
I'm having the same problem on my Fedora Asahi installation (M1 Macbook Air 2020), and noticed that the widgets stop displaying if I: 1. Open the widget (such as the System tray, Sensor, Calendar and Kickoff) 2. Click on another opened window (in my case, I've tested this with Firefox, Dolphin and System settings) 3. Try to open said widget, but then it doesn't come up The bug can be avoided if I click the widget button to "manually" close it. Sometimes, even the Hover Task to Preview action stops working. This occurs when I hover over active tasks and then move the pointer to applications that have some kind of interactive highlighting of UI elements, like Firefox hyperlinks or Dolphin displayed files, all of this quickly enough to do it before the Preview closes.
