Solution to FLEx 9.0 Flatpak theme incompatibility

[tdavli...@gmail.com]

Hello all,

I use FLEx 9.0 on Linux Mint 22.1 (latest) via the 9.0 Flatpak version. Upon installation, it was clear that it would not play nice with my dark GTK theme and no matter what I did, it would not conform properly, to the point where the top toolbar text was basically unreadable. The solution was to set the GTK_THEME environment variable to <space>, essentially blanking it out, which can be done either on the command line:

`sudo flatpak override org.sil.FieldWorks --env=GTK_THEME= `

`sudo flatpak override org.sil.FieldWorks --env=ICON_THEME= `

(be sure to omit the `` if copying and pasting the commands)

Or by first installing Flatseal and setting the environment variable under Fieldworks there. (see attached screenshot for example)

After doing that, FLEx always starts with its default Windows 2000-esque gray theme and all of the colors etc are legible, despite being in light-mode. :)

Hope this piece of advice is helpful to anyone who might have or might be experiencing a similar issue to me.
