I forgot to mention, submenus of such broken submenus will also no longer open up when this bug happens. As a consequence it's more than just an annoyance, it actually makes some of the deeper menus really hard to access since this seems to happen 30% of the time a submenu opens, and therefore it has a high likelihood of happening at least once descending into a deeper nesting chain. I can reproduce with Kate 20.08.2 running natively on Wayland on Arch Linux + Gnome 3.38.1. Possibly a Qt bug. Confirmed by Patrick. One variant of that is now fixed with https://invent.kde.org/frameworks/kxmlgui/-/merge_requests/284 For more I think we need a Qt fix https://bugreports.qt.io/browse/QTBUG-137467 This is now fixed in Qt and will release with 6.9.2 and 6.10. |
Created attachment 129565 [details] brokenmenus.png: the broken submenus (backgrounds blurred out for privacy) SUMMARY kate's menus are occasionally broken under GNOME 3, may pop up anywhere on screen. This happens both with Fedora's natively packaged kate 19.12.2, as well as FlatHub's kate 20.04.2. STEPS TO REPRODUCE 1. Install GNOME 3 as packaged on Fedora 32 right now 2. Start a GNOME 3 Wayland session (not sure if it reproduces with the Xorg one, probably not) 3. Install & start kate from either flathub or repositories 4. Keep opening sub menus until issue appears, it happens around every 30% of the time OBSERVED RESULT See brokenmenus.png: the broken submenus in a screenshot showing the problem. (backgrounds blurred out for privacy) Also, the following shows up in the terminal output: qt.qpa.wayland: setGrabPopup called with a parent, QtWaylandClient::QWaylandXdgSurface(0x55761166f0c0) which does not match the current topmost grabbing popup, QtWaylandClient::QWaylandXdgSurface(0x5576120f2d40) According to the xdg-shell protocol, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly because xdg-shell mandate that child popups close before parents EXPECTED RESULT works / no menus placed kinda randomly on the screen SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Fedora 32 with GNOME 3.36.3 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: various, see flatpak/flathub release for one of them ADDITIONAL INFORMATION
