In the latest WIP `TestMooCow` is “acting up”:

Also, `SynchronizeViews` only updates 2 orthographic viewports (in a standard 4 viewport setup) - the one that one is working with and one other. The 3rd orthographic viewport does not follow along.

Hi Wim,

In some brief testing I have not been able to repeat what you are reporting about SynchronizeViews. What do I need to do to be able to repeat this?

I’m unable to repeat this on another PC… And I’m not sure why exactly I wrote `SynchronizeViews` there - I was using linked viewports in the **_Rhino Options \> View \> Linked Viewports_**.

I was only trying that because of the issue with `TestMooCow`. I have seen viewports not refreshing for a longer time now and while annoying to a certain degree, it’s just a matter of waking up the other viewports.

The thing with `TestMooCow` is worse. That one I am also reproducing on the other PC.  
I often have a floating viewport on a secondary screen with a shaded display mode and a maximized viewport on the main screen with a wireframe display mode. Both perspective. Having these viewports linked works wonders but that stopped working now…

Hi Wim,

I guess I’m not sure what is being described here. Is there an action to be taken here?

Yes please. I need `TestMooCow` to work again.

- Launch Rhino
- Maximize the perspective view - shaded display mode
- Make a cube centered at world 0
- Call `NewFloatingViewport`
- Call `TestMooCow` and pick the floating as primary, the maximized as secondary.

On my system this is what I then see:

You can see the one box 3 times but there are only 2 viewports.

Rotate the view in the floating viewport and now this is what I see:

As I said, I can replicate this behavior on two completely different systems so I hope this is not something that I’m the only one that is seeing.

Hmm - it worked here… I think… checking again… oh, yeah, I see, right, not actually very handy.

Hi Pascal,  
From what I found out now, it works very well as long as the viewports have exactly the same size. On 2 identical screens, my one viewport will be within the Rhino interface and the floating viewport on the second screen will be bigger…

Yeah, that is what I found as well - my guess is it’s not hard to fix but…
