control: tags + patch
Hello,
unfortunately upstream had dropped Qt altogether,
but had no release the last years.
I tried what happens if simply avoid all "QX11Info::display()"
by returning early if "QX11Info::isPlatformX11()".
This makes it kind of playable in a short test,
but mouse look is not possible because of following message:
qt.qpa.wayland: Setting cursor position is not possible on wayland
So I made another attempt to set QT_QPA_PLATFORM=xcb if a Wayland session is
detected,
like it is done e.g. in FreeCAD or others [1], see attached patch.
Kind regards,
Bernhard
