I may have found a solution. I think, there must be something around the fonts used by the game. So, I copied a lot of fonts from my Fonts folder to the "[GameFolder]\Font" folder (typically it's the "C:\Program Files\Stardock Games\Sins of a Solar Empire\Font\" path). And then, I edited the ListItem.font file, like this:
TXT
Font
Height 14
TypeFaceName "impact"
You can see, the TypeFaceName property must be changed with the appropriate name of the new font, wich is the file name of that without the extension.
The game doesn't support a lot of kind of fonts, only the Arial-like ones, the Nina-family and the Impact were what I had success with. Now, I'm using Impact, it's the closest to the original SinsAgencyBold font.
The game runs much more flawlessly after changing the font.
(A note: you may do the same with the PlanetNameMainView.font file, too.)
I hope, it's helpful as for the gamers solving their problem as for the developers finding the real cause of this issue.
