Thanks. I've skipped some of your questions that were unclear to me. David
might be able to help since he did the testing if I read this correctly.

Are you using a patched runtime with our GC7000 mesa patches? If not there will
be rendering issues. There's lots of stuff upstream already but some
core parts are missing that are required for proper texture
rendering. You should see a notable difference between pure maps
as flatpak and pure maps built natively on the devkit / qemu image. If
not please let me know.

I've filed

https://source.puri.sm/Librem5/Apps_Issues/issues/135

since this comes up here and there and i think there was no bug for it yet.

So nothing to worry about if you provide a desktop file.

Can you be more specific. Do you expect polkit authentiction? If so

https://source.puri.sm/Librem5/phosh/merge_requests/213

does fix the shell side but we need to fix

https://source.puri.sm/Librem5/phosh/issues/34

for this to work (it basically works if you launch the compositor from
the console when logging in instead of the systemd unit).

This depends on your app. You need to provide more details. Are you
rendering via x11 or wayland? Is there a simple one line test case to
verify this (without installing pure maps)? By default all x11 surfaces
are decorated. You should be rendering via wayland when possible.
