"Spin" behavior on dual monitor setup

When I “spin” an outline of an object I get different results from using a single monitor setup or dual monitor setup (My system specs are in my bio)

Heres my procedure for both attempts:

From Object mode, select all, delete scene, create plan, go to edit mode, delete plane.

Go to front orthographic view (1,5), create outline that I will “spin” into a cup or glass. I make sure the cursor is in the center of the screen (SHIFT+c) and the ends of the shape do not pass over the center point.
(see screenshot, I’m on Object mode ONLY to show the outline of the object clearly for the screenshot)



I select all (a), I switch to top orthographic view (7,5) then click spin in the transform tools, changing the degress to 360 and on a single monitor it does exactly what you see in the second screen shot.

If I move my viewport to a 2nd monitor (shift, LMB) and do this exact method two things happen

  1. I have to click “spin” twice, the first click does not register
  2. the outcome is spinning the wrong axis and it does not look ANYTHING like the screenshot I’m showing (I don’t have a screen shot, I’m at work on my Mac with same version of blender but I can’t justify $40 for a DVI adapter since my job won’t reimburse me for personal use purchase for their equipment that they can replace in a heartbeat.)

Has anyone else seen this? Is this a bug or a design by nature to do this?

Hi strat,

I may not be doing this exactly the same way you are (I’m unsure what you mean by shifting the viewport to the second monitor using Shift-LMB, so I just dragging Blender from one monitor to the other).

My results were the same on both. If there’s something I’m missing in your procedure, let me know.

I’ve got palettes in both monitors, so viewport is moved to the larger screen the tools are in another. If I drag EVERYTHING over into the same monitor it works properly, it’s when both monitors are being used at the same time.
