Yes. I can confirm, it works even on Gentoo. But I stick to the Flatpak version, anyway, because there I was able to tell it to use Xwayland instead of wayland directly (through Flatseal).
It seems the wayland support isn’t great yet and it tries to grab keys combination that are reserved for my window manager (Gnome). In the flatpak sandbox I don’t have any issues.
Only game running game detection will not work in the sandbox.
Or is there even a setting to tell it, using the X11 backend so that the keybind issues for the native version go away?
There seems to be a global option to reduce opacity, too. Anyway, I agree, contrast and readability is a problem with ideas like that.
Now, Phosh and Gnome look even better and more usable in comparison. But without Android apps or open APIs for all major services (to build native apps), postmarketOS can never be my daily driver for now.
At least, iOS changes like that increase the chance that the postmarketOS ecosystem will catch up. I whish I had the time or ressources to contribute in any fashion.
