Since yesterday, the game ‘stutters’ when I scroll or move back and forth in the picture. Yesterday it was only with picture no. 15, today it has already started in the menu. Painting like this is no fun because I find it very tiring :/

I had this a few months ago, but it was gone after a few days, but I don't want to wait days now (doesn't make much sense for an advent calendar :'D)

Has anyone experienced this or does anyone know how to solve the problem? Reinstall the game maybe?
