NO_STRIP=true ?

Yes, that fix works as far as I can tell.  I already had the latest Nov. 7, 2026 linuxdeploy release.
Now I am building again with the Vulkan_wip patch in and the ffv1_vulkan.mov render format in so I can find out if this AppImage will work for Terje.  If so, then can add to the general releases in the future too.
