I have succeeded to start the app without Xwayland thank's tu qtubuntu-qt .
The "Terms and conditions" Window displays well and works well, but then the main window appears for 2 sec and crashes with:
Feb 24 13:43:05 ubuntu-phablet aa-exec[31163]: Aborted
Feb 24 13:43:05 ubuntu-phablet aa-exec[31165]: CHECK(!m_acquiredFrame->isBound())
Feb 24 13:43:05 ubuntu-phablet aa-exec[31165]: qt_common/qtoglcontext.cpp:108
Feb 24 13:43:05 ubuntu-phablet aa-exec[31165]: (1) ASSERT FAILED
I think I will leave it here for now. I think for this app to be usable it would require:
- To wait for Qt6 and possibly Mir2.x to be properly integrated in the system
- That Organic Maps get a Qt app more adapted to mobile display.
