When I try to start Falkon in a wayland session it shows the window for a split second and then crashes. The output I get from a terminal is: michael@michael-Lenovo-YOGA-710-15IKB:~$ falkon Using Wayland-EGL WebEngine compiled with X11 support, however qpa backend is not xcb. This may fail.

Core file will not be generated. I see there is an error regarding the "OpenGL implementation", which might be due to the fact that I'm running mesa from git (18.1.0, padoka), but I've no idea really. If I recall correctly, I had Falkon running just fine from opensuse tumbleweed in a wayland session.
This is a Qt issue, see https://bugreports.qt.io/browse/QTBUG-65682. As a workaround, run it with QT_QPA_PLATFORM=xcb
Thanks! I suppose this should be marked "resolved, upstream"?
