Glyphs (804) window turns invisible after switching between apps

Sometimes, when I switch back and forth between glyphs and other apps, and I have several font files open, one of the windows disappears. The file would still be open but the window is not visible anymore.

I have had this happening to me several times now… anyone else?

Can you check if you find anything in the console.app?

I’ll check for that next time it happens…
