mwp crashes when window is closed

[snaewe]

mwp crashes when I just close the window using the "x" icon. Ending via menu or shortcut CTRL-q works as expected.
I'm on Linux Mint 20.3. Here's the terminal output if that helps:

Perhaps predictably, this cannot be reproduced on a supported Debian derivative OS (Ubuntu LTS, Debian Stable).
If you wish to take this further:

• Run it in gdb, provide a backtrace (bt) when it crashes.

    meson reconfigure --buildtype=debug
    meson install -C build
    cd build/
    gdb ./mwp

So it dies deep in Mint's OpenGL libraries.
Mint is not a supported environment; so it's a WONTFIX.
