Created attachment 177010 [details] contextual menu issue SUMMARY When context menu is invoked for the first time on the title bar of a window, sub-context menu is partially (nearly totally?) a « ghost » version of itself (truncated and a problem of transparency, I mean). The record in attachment shows the issue better than I describe it. STEPS TO REPRODUCE 1. login to plasmashell 2. open an application 3. right-click on the title bar of the corresponding window 4. navigate through the contextual menu from top to down OBSERVED RESULT sub-contextual menu is not fully showing itself. EXPECTED RESULT sub-contextual menu is fully showing itself. SOFTWARE/OS VERSIONS Operating System: Gentoo Linux 2.17 KDE Plasma Version: 6.2.4 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.1 Kernel Version: 6.12.7-gentoo-x86_64 (64-bit) Graphics Platform: Wayland Processors: 8 × Intel® Core™ i7-9700K CPU @ 3.60GHz Memory: 31.3 Gio of RAM Graphics Processor: AMD Radeon RX 7800 XT ADDITIONAL INFORMATION The issue happens only once during the session; only on the first window where contextual menu is invoked. If the contextual menu is navigated from down to top (instead of top to down), the sub-contextual menu reappears! And the bug doesn’t show anymore during all the session, on any window. This bug exists since many versions, I reported it here only today because now I have time to do it.
In addition, I have tested also under X11, the issue does not appear on X11. Only under Wayland.

I remember fixing something with a kwin menu a while back, but i now can't find a link. I definitely cannot reproduce anymore. Please confirm if this is still an issue with Plasma 6.3 and reopen if not.
