I got the game yesterday in order to play with a friend of mine. Unfortunately, it seems that the GOG overlay for both of us will not respond to any inputs. The overlay, whether opened via find friends in the game menu or shift + tab, opens but does not respond to any inputs. Has anyone else experienced this issue before? I have not done multiplayer in GOG prior so I don't know if it's limited to this game alone or a more common issue. Thank you for the help

Same here and for me it takes long time till the overlay even opens ...

"Similar" issue for a friend. Friend list shows always offline on the game and the MATCHMAKING menu is greyed out even tho friend list acts normally on the client.

I take a pretty good FPS hit while running the game with Galaxy. There are some overlay issues here for me as well.
