During application startup, launch was aborted and an error related to TRANSLUCENT popped up in Linux systems where the window manager lacked translucency support.
This issue has been fixed in 1.42.11 version. Softagram will work in both window managers: with and without translucency support. Please update the app using the usual procedure (as asked when starting up).
