Short description of error
Continuous Grab with a pen goes bananas.
Long description of error
Years ago an exception was added to Continuous Grab so it would be temporarily disabled if it detected pen input, because it simply didn't work well (transform went crazy). That way it would always work properly. We could keep Continuous Grab on for mouse use and it'd be ignored if we used the pen to tweak a slider or orbiting the 3D Viewport. It seems that the stylus detection is not working anymore.
Exact steps for others to reproduce the error
- Factory startup.
- Simply rotate the viewport or transform the cube with the stylus past the border of the editor.
