Pan view in sculpt-mode

Hello,

Everytime I use sculpt-mode and try to pan the view with the middle mouse, the pan-movement is extremely sensible! I have to move the mouse pixel by pixel otherwise the view pans at a extremely high rate… this seems to be when I pan and the mouse is hovering above the object I am editing. When I press the middle mouse to pan, when I am not hovering above the object it seems to drag the view normally.
Is this a know issue and how can I prevent this?

Hope someone can help me out… thanks in advance for help!

Greetings André

Switch your view to orthographic, that problem only happens with perspective.
