"scribbling and dotting all by itself" doesn't make sense.
Photoshop can only paint where you tell it to paint, unless there's a serious problem with a mouse or tablet driver.

Is the slow document different in some way from other documents you work with? Larger? More layers? Using video or 3D?

Have you installed all the Photoshop updates?
What OS version are you using?
Do you have any third party plugins, and have you tried disabling them?
