When integrating the AppImage using AppImageLauncher, Musescore logo is not shown in Ubuntu dock
1) Start the Musescore appimage with AppImageLauncher installed on Ubuntu.
2) Choose to integrate the Musescore appimage.
3) Observe that the Appimage launcher in the dock does not have a logo.
Other applications that distribute via AppImages, for example Krita, do have logos when integrated using AppImageLauncher. I am reporting this issue here rather than to the AppImageLauncher developers because I believe that this may be an issue on Musescore's side, as Krita's logo does show up.
