SUMMARY Typing "Shut down" and selecting it in overview, when Logout Screen is enabled, will freeze Plasma session STEPS TO REPRODUCE 1. Make sure Logout Screen is toggled on in Desktop Session settings 2. Open overview 3. Type Shut down/logout, anything that opens the Logout Screen OBSERVED RESULT Plasma freezes. It takes some time but usually starts working again after some waiting. EXPECTED RESULT Overview would close and Plasma would not freeze SOFTWARE/OS VERSIONS Operating System: Fedora Linux 39 KDE Plasma Version: 5.27.9 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 Kernel Version: 6.6.2-201.fc39.x86_64 (64-bit) Graphics Platform: Wayland Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 15.5 GiB of RAM Graphics Processor: AMD Radeon RX 6600 ADDITIONAL INFORMATION This also happens in Plasma 6. I think it's very likely due to Overview effect and Logout Screen effect colliding somehow. It feels like Overview effect is not closed properly when Logout Screen appears.
This is a dev session issue; the same one that causes the logout screen to appear blank when triggered with any of the UI elements that show it, rather than running `~/kde/usr/lib64/libexec/ksmserver-logout-greeter --windowed` manually to force it to launch the Plasma 6 version of the binary. This was discovered by reproducing the bug as you described it, and then later entering `~/kde/usr/lib64/libexec/ksmserver-logout-greeter --windowed` in the Overview effect's search field; that works properly. Thus it is a duplicate of Bug 462824. *** This bug has been marked as a duplicate of bug 462824 ***
