Can't view Glyphs at all in FontCreator using Wine

FontCreator - Font Editor FontCreator - Bug Reports
1

When I open a Font, all the Glyphs are completely blank and only shows outlines in the editor which make this program unusable no matter when I try every Fonts.
I switch to Linux and currently try to get it to function properly myself, but nothing changes.

Can you try the light theme?

Or in options force light colors?

Tried that and still no difference.

Maybe you accidentally changed the Glyph Display Mode from the View menu? If it is set to Color it will show empty slots as your font has no color glyphs.
