City Engine 2015.2 viewport issue on extension monitor

Question

I am working on cityengine 2015.2 on a Macbook Pro, with extended display on a Dell Monitor.

When I open cityengine and view it on the monitor, I have problems selecting objects in my scene. When I click an object,  another object somewhere far away is selected. There seems to be a problem with display projections. Everything else in the navigation panes and windows works okay on the monitor. The problem is only in the viewport. It also works okay if I place my cityengine window on my Mac screen. This issue only occurs on the extended screen when working in the viewport.

Also, I have been using CityEngine 2014.1 for while with the exact same setup and never encountered this issue before. So I am guessing there might be some compatibility issue with 2015.2

I really don't want to work on my tiny Mac screen, so I would appreciate any pointers. Thanks!

Hello Thomas

Thanks for your quick response. The problem has resolved itself, and I am not sure what went wrong in the first place. But I'm glad it worked out.

Hello Tanvi Maheshwari,

Thank you for your report.

I tested CityEngine 2015.2 for the issue you described, but was unable to reproduce. Selecting shapes in the viewport was accurate on the external monitor.

Here is my setup:

* MacBook Pro (Retina, 15 inch, Mid 2014)
* OS X 10.10.5 (Yosemite)
* Monitor with 2560 x 1440 native resolution (extended display)

Could you please provide more information on your system?

Also have a look at the compatibility settings for Retina Macs in OS X:
