Shared Memory Error: Can't run Firefox & Falkon

[8itlew7r]

I'm encountering an issue with shared memory on my non-rooted Android phone running AnLinux Debian rootfs armhf. Despite a potential lapse in installing shared memory APIs emulation, Xwayland seems to be functioning.

I attempted an upgrade to bookworm, but the problem persists. Any insights or guidance would be greatly appreciated.

On the session running Xwayland (I have a hard time describing the screenshot below), there is an error that seems to occur only specifically when trying to start firefox-esr. In addition, the Falkon release on Debian bookworm presents a bug related to /dev/shm permissions, with a suggested solution of changing the permission of this path to 1777.

I'm not sure if this is relevant, but I got an stderr message while running ( S=install-libwrapdroid.sh ; "$TERMSH" copy -f -fu "https://raw.githubusercontent.com/green-green-avk/AnotherTerm-scripts/master/$S" -tp . && chmod 755 $S && ./$S )

The problem persists, and I have a hunch that it could be connected to the shared memory API.

The problem persists in the same way or something have changed?

I'm sorry, but the problem persists in the same way. I was wondering if, by any chance, it might have worked on your end, maybe with some emulation of my device properties?
