Hi, i have a Problem with this Error- Massages in the Mate- Terminal.
If i start fastgame from Terminal it says:

(fastgame:19050): Adwaita-WARNING **: 23:05:12.568: No known Yaru accent 'MATE'

(fastgame:19050): GLib-GIO-ERROR **: 23:05:12.569: Settings schema 'com.github.wwmm.fastgame' is not installed
Trace/Breakpoint ausgelöst (Speicherabzug geschrieben)

then it close...

Can You please help me? I don't know what i did wrong...

Settings schema 'com.github.wwmm.fastgame' is not installed

How did you install FastGame? Or are you running directly from the build folder through a binary you compiled yourself? Depending on what you are doing just running glib-compile-schemas as root should be enough. But if you are not running from a system installation you may have to run glib-compile-schemas with the correct path as argument as well as exporting some environment variables.
