I did a search. Can you try this workaround?

export XDG_DATA_DIRS="/usr/local/share:/usr/share"
echo $XDG_DATA_DIRS
./XXXX.AppImage

[superiums]

thanks for suggestion, i've tried to set XDG_DATA_DIRS, but not work.
also i've tried to refresh mime cache, still no lucky.

Modern themes use svg for icons.
It seems like 'libpixbufloader-svg.so' is missing in the appimage, so it fails to load theme resources.
