Is "Plugin "GTK3 plugin" uses conflicting symbol "png_free"." the last message?

That's really a strange one. PPSSPP does not link to GTK, as far as I know.

Similar to this blender issue? https://projects.blender.org/blender/blender/issues/108308

This looks to be caused by: https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/47

Besides this being resolved by libdecor, the only solutions I'm aware of - is to use a different libdecor plugin, disable libdecor entirely or use X11 instead of Wayland.

See https://docs.blender.org/manual/en/3.6/getting_started/installing/linux_windowing_environment.html for disabling libdecor and forcing X11.

And libdecor issue https://gitlab.freedesktop.org/libdecor/libdecor/-/issues/47

That's a "feature". Libdecor checks for conflicting symbols to prevent crashes when a plugin and the application use the same functions that may conflict. Since GTK uses the png library, the GTK plugin defines a conflict for png_free.
In such a case, libdecor should select the next plugin, which should be the cairo plugin.

I tried using x11 with Flatseal. It only does the same thing. I don't get libdecor errors.
