I am not 100% sure whether xdg-shell availability is the blocker. There is
something going on which I cannot explain yet - its as if Wayland rendering
disappears even when I use qxcomposer.
qxcomposer does allow me to minimize and then restore. However, when
keeping app minimized and switching to other apps, I do get (with
[2294832.935] wl_pointer at 8.motion(207667, 0.000000, 0.000000)
[2299966.213] qt_extended_surface at 29.onscreen_visibility(1)
[2303645.301] qt_extended_surface at 29.onscreen_visibility(0)
[2303647.486] -> wl_surface at 26.destroy()
[2303648.296] -> wl_buffer at 4278190080.destroy()
[2303648.395] -> wl_buffer at 4278190082.destroy()
[2303648.448] -> wl_buffer at 4278190081.destroy()
and the app window disappears from qxcomposer.
Same happens when running directly using SFOS composer:
[2614530.331] qt_extended_surface at 29.onscreen_visibility(0)
[2614552.802] -> wl_surface at 26.destroy()
[2614555.653] -> wl_buffer at 4278190080.destroy()
[2614556.795] -> wl_buffer at 4278190082.destroy()
[2614557.099] -> wl_buffer at 4278190081.destroy()
So, looks like the surface gets destroyed, but nothing really restores it.
As such, some kind of wrapper, similar to qxcomposer, around Flatpak
programs maybe handy. It could take few tasks, such as
- follow orientation of the screen
- restore app after wl_buffer.destroy()
- provide keyboard support
I don't know enough about Wayland to be efficient in working on it. So, I
wonder if someone would like to step in and help with this part. If there
is interest, I will work on packaging libhybris extension and provide an
example at OBS for Xperia Tama devices.
