My Kickoff menu (Start menu) on one of the screens is binded to the Alt + F1 shortcut. The kickoff menu may have three variants (alternatives). Mine in this monitor is configured as Whole screen (the big icons on the black blur background). I am on Wayland session. This monitor is configured so it scales 200% (UHD monitor), while the other monitor is 100%. When I press Alt + F1 single time, I can see a "small lag" - the start menu is not immediately drawn. For a fraction of a second the icons appear with the wrong scale (not 200% scale), and after a bit of time, it is finally shown. Now, if I will press Alt + F1 several times in a row (I guess, it triggers cancel when it is in the middle position - already activated, but not yet drawn fully), the Plasma desktop "crashes". Applications stay opened, but I see that panel disappears, and after some time appears again (plasma self recovered). Now, if I will press and hold Alt + F1, then plasma is going to state where it cannot self-recover anymore (the panel is no more shown).

Does it happen with any other launcher menus, like Kickoff or Kicker? Can you attach a symbolicated backtrace of the crash?
Cannot reproduce with Kicker or Kickoff, but I can reproduce the crash fairly instantly with Application Dashboard. The backtrace looks fairly unhelpful, though: (gdb) bt #0 0x00007f2365125bcd in __GI___poll (fds=0x6e5afd0, nfds=18, timeout=1661) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007f236451deb4 in g_main_context_poll_unlocked (priority=2147483647, n_fds=18, fds=0x6e5afd0, timeout=<optimized out>, context=0x7f234c000ef0) at ../glib/gmain.c:4653 #2 g_main_context_iterate_unlocked.isra.0 (context=context@entry=0x7f234c000ef0, block=block@entry=1, dispatch=dispatch@entry=1, self=<optimized out>) at ../glib/gmain.c:4344 #3 0x00007f23644c0ad3 in g_main_context_iteration (context=0x7f234c000ef0, may_block=1) at ../glib/gmain.c:4414 #4 0x00007f2365a4096f in QEventDispatcherGlib::processEvents (this=0x1893c40, flags=...) at /usr/src/debug/qt6-qtbase-6.6.0-6.fc39.x86_64/src/corelib/kernel/qeventdispatcher_glib.cpp:393 #5 0x00007f23657ad9bb in QEventLoop::exec (this=this@entry=0x7ffd8423a690, flags=..., flags@entry=...) at /usr/src/debug/qt6-qtbase-6.6.0-6.fc39.x86_64/src/corelib/global/qflags.h:34 #6 0x00007f23657a97bd in QCoreApplication::exec () at /usr/src/debug/qt6-qtbase-6.6.0-6.fc39.x86_64/src/corelib/global/qflags.h:74 #7 0x00007f2365ff8b4d in QGuiApplication::exec () at /usr/src/debug/qt6-qtbase-6.6.0-6.fc39.x86_64/src/gui/kernel/qguiapplication.cpp:1921 #8 0x00007f2367dc2aa9 in QApplication::exec () at /usr/src/debug/qt6-qtbase-6.6.0-6.fc39.x86_64/src/widgets/kernel/qapplication.cpp:2569 #9 0x0000000000425f4f in main (argc=<optimized out>, argv=<optimized out>) at /home/nate/kde/src/plasma-workspace/shell/main.cpp:214
Can't reproduce this. I'm on Wayland.

If we can't reproduce this, I will close it as resolved.
