I am just starting to play with things but a quick thing I just noticed is that when I re-size my window by dragging with the mouse or going full screen, the mouse pointer for the pen tool will not track 1to1 with my pen tool pointer on the grid.
When I move the mouse up and down along the center of the window, the 2 will be together but as I move to the left and right, the movement of the tool slower then the tool.
if I re size the window to be really thin, the left/right movement will be faster then my mouse movement.
I can fix the problem by seizing the window in a perfect square.
This does not affect my ability to interact with other UI elements or to select things in the scene.
