Standard Fedora 31 x86-64 Gnome Wayland. If you open, for example, a video file with two audio tracks with mkvtoolnix-gui and try to reorder those two audio tracks by dragging track 2 higher than track 1 the interface doesn't react. Doing the same in Gnome on X11 works just fine.
Same thing happens with ksysguard when trying to create a new graph by "Drop Sensor Here".
So, our current educated guess for Qt5 applications misbehaving under wayland, is that these are application bugs that should be fixed there, and not something in qt5-qtwayland. (Triaging to mkvtoolnix) One short-term workaround applications can do is to use xcb plugin (instead of wayland).
Not sure where is the problem, but I tested ksysguard in Weston with QtWayland and DnD works there just fine. It might be Mutter + QtWayland combination which is problematic.
FWIW I also used Gnome/Wayland in Fedora 30, which AFAIK doesn't have any big difference over Fedora 31. Neither mkvtoolnix or ksysguard had a problem in there.
Oh, and this is a brand new installation. I didn't upgrade from 30 to 31, I wiped 30 and installed 31 from zero.
Fedora 30 doesn't use qtwayland by default, you would have to run mkvtoolnix or ksysguard with "-platform wayland" argument.
Oh OK, I didn't use "-platform wayland". So ignore my previous comment.
moving back to qt5-qtwayland
and running QT_QPA_PLATFORM=xcb mkvtoolnix-gui ?
With QT_QPA_PLATFORM=xcb it works just fine.
Qt stack including kf5-kwayland-5.64.0-2.fc31 has been pushed to stable , can you update all Qt stack , and test it ? please , I heard that have some fixes for wayland Thanks
Still broken.
