Brush strokes don't work properly

When I make a brush stroke it doesnt want to end properly, even though i use normal round brushes with standart settings. I have tried all sorts of solutions, from reinstalling photoshop to getting a new graphic tablet. I dont know what to do anymore so I post it in here.

On the photo you can see that i use normal brush, with no additional settings and strokes are still cursed on the end. It repeats with every brush, so you know.
