Debian Testing/10/Buster running OpenShot-v2.4.2-x86_64.AppImage
Here is the startup log this shows that the
stabilize filter is read, but never added: https://gist.github.com/mattcollier/cea89bda90a356e3d3f6996ece8f369a#file-shotcut-txt-L567
Stabilize does not show up in the list of filters when I have a video clip selected. GPU Effects are disabled (if that is still required).
Is there some additional debugging that can be enabled to get more information about why the filter is not loading? Would building from source likely address the issue?
