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
