Organicmaps broken since Qt6 update

Hello!
Has anyone solved the issue with oranicmaps shows only triangle?
[desktop][drape] Black screen with new Qt 6.7 · Issue #7838 · organicmaps/organicmaps · GitHub

I tried to build qt6-base-git to check if the qt bug is solved but had a build error:
install: omitting directory ‘qtbase/LICENSES’
==> ERROR: A failure occurred in package_qt6-base-git().
Aborting…
:: Unable to build qt6-base-git - makepkg exited with code: 4

can anyone help how to get more info about this exit code?
thx!
does anyone know a good alternative to organicmaps? I need offline map support.

Using AUR packages can often expose you to this kind of lib incompatibility for the application you like, after a system update.
Over years, I try to avoid AUR if the same package is available via Flatpak or AppImage, if it is not contained in official repositories.

AFAIK, Organicmaps is also available via Flatpak:

Even Google Maps allows you to download an area of your choice when you are connected
for use when you are not. :man_shrugging:

I use that feature all the time.
(you can’t build routes in offline mode
but the maps are there …)

I just built organigmaps-git
It took a long time - a very long time to fetch all the code
and about equally as long to build it (a VM on a not very high powered host)

But I can’t begin to use it - the window is just black, no map is displayed. :man_shrugging:
