Created attachment 165165 [details] Screenshot of fullscreen menu SUMMARY When using layer-shell-qt in application which uses QMenu widgets, warning "layershellqt: Cannot attach popup of unknown type" is written on menu activation. I assume it occurs in QWaylandLayerSurface::attachPopup(QtWaylandClient::QWaylandShellSurface *popup) method. The bad thing about it is that menus break, actually. Without layer-shell-qt they work perfectly fine and only when I call LayerShellQt::Shell::useLayerShell() they go fullscreen and hard to navigate. STEPS TO REPRODUCE 1. Integrate layer-shell-qt into project 2. Create any QMenu OBSERVED RESULT Menu goes fullscreen. EXPECTED RESULT Menu stays normal, as in Qt without layer-shell-qt enabled. SOFTWARE/OS VERSIONS Linux: 6.6.11 Qt Version: 6.6.0 ADDITIONAL INFORMATION Screenshot of fullscreen menu attached.
Example code: https://codeberg.org/stolick/stolick You don't have to edit anything, I committed problematic code in master branch.
Are you building with clang? This sounds like https://bugs.kde.org/show_bug.cgi?id=479679
(In reply to Nicolas Fella from comment #2) > Are you building with clang? This sounds like > https://bugs.kde.org/show_bug.cgi?id=479679 Hi, Nicolas! Thank you for a reply :) I just tried to build with clang like that: export CC=/usr/bin/clang export CXX=/usr/bin/clang++ cmake -B build cmake --build build CMake said that it's using clang and it built successfully but the bug persists. I still get "layershellqt: Cannot attach popup of unknown type" message and QMenu objects continue to go fullscreen. In case you want to test this code with my example and layer-shell-qt module enabled you have to build against https://codeberg.org/stolick/stolick/commit/5c70e291d4ee4a07b2bfb388a3fce2f926994c13 commit (named "use broken layer-shell-qt for a while"). Best regards, Grigory.

Does your clang use libc++ or libstdc++? The former will trip this bug.
