Problem with pen and brush tools

Hi! I'm writing because for a few days now, I notice that the strokes of the line drawing tools shift slightly after drawing them. They change their position slightly , and it happens to me both with the mouse and with the tablet, so I don't think it's a question of the drivers. I've tried changing the device scaling, but it still doesn't work. If anyone can help me that would be nice, it is very frustrating to animate like this.

Thanks and best regards!
