I had that problem a year or so ago. Apparently, Facer has not been able to find the bug yet. On my Fossil all the text deteriorated more each day. Needless to say, I no longer use the stroke feature. The only suggestion I can offer is to use a font that is already outlined so you do not need the stroke.
Thank you! Do you know if that is only Fossil issue? This is severely limiting what can be done, especially since most fonts don’t have “outline” version since any vector program can make outlines anyway.
I don’t know if it was limited to Fossil (I had a Gen 4 Venture.) Even if it was, I didn’t want anyone else to have that problem, so I make sure I’m not using stroke.
