Hello. I'm having a problem with photoshop in which I can only draw lines at an angle. I can't seem to find a fix that works and I don't know what is causing the problem being that my tablet (Ugee-2150) works fine with everything else but photoshop. I tried multiple fixes yet none of them work. Can anyone help me?
In normal use, a Photoshop brush will draw lines at an angle when the Shift key is held down. Most tablets let you configure how the stylus works, including whether a modifier key is held down, so if you haven't done this already, check your tablet driver settings to see if the Shift key is set up to be applied for any stylus actions (e.g. mouse down, primary button pressed, etc.).
I don't know anything about the Ugee-2150 tablet specifically, so if that doesn't help, i don't know what else might fix the problem other than making sure the tablet driver software is up to date, or resetting the preferences file for the tablet driver software.
