In Windows are you using any mouse software or settings, like Mouse Trails? If so please set the cursor to the default Windows setting before starting the game.

I've never seen anything else cause this.

Has it always been the case in this game for you? Or it was okay up to some point?

Our similar game Cruisader Kings 2 is free to play on Steam, do you get the same problem there?

What if you make a new Windows user and log into Windows as that - does it still happen?

I've seen reports of this with CSL on Epic only, no other game. My best guess is it relates to some change in the Epic client but I haven't been able to prove that.

@Jamface662 Unload the Epic client entirely then run EU4.exe by itself. Does this still happen?
