RawTherapee 5.4 AppImage font issue

@Carmelo_DrRaw Okay so I did what you said to do. It’s running, but no difference in behaviour. Some things are a tad choppy, and it feels like its taking a fraction of a second to think about what it needs to do before implementing it …like for example changing the Brightness slider in RGB mode. Would the Warnings on the right in command line regarding Gtk have anything to do with it.

My installed debian 5.0 runs way smooth, but it’s GTK2 compiled.
