I was working with Synfig normally in Linux Mint 22.2 until yesterday.
I needed to reformat and install Linux Mint 22.3. I installed my typical AppImages: Krita, Inkscape, and appimagelauncher: GitHub - TheAssassin/AppImageLauncher: Helper application for Linux distributions serving as a kind of "entry point" for running and integrating AppImages (it creates the menu entry and icon for all appimages).
I found that the Synfig Appimage cannot start while the appimagelauncher (DEB version) is installed. Running the Synfig appimage from the terminal reveals: “Can’t open /tmp/.mount_NNNN/…”
I uninstalled it and Synfig ran fine again. It created its font cache in first run and started.
I did some experiments with appimagelauncher Appimage version and it was a little better. But I stop my story here…
Is appimagelauncher known to interfere with Synfig? Is there a way to make them work together smoothly. If not, I would be OK with just leaving appimagelauncher.
