CityEngine not responding when opening a new scene

[CarlBesterEsriZA]

After a couple of years, I recently installed CityEngine 2022.1 to get back into it, but every time I try to open a new scene the entire CE application becomes Not Responding. 

I remember in an earlier version it did something similar but can't seem to find the post.

Any suggestions will be appreciated.

Thanks Simon.

Adding -Dglsinglebuffer to the CityEngine.ini file worked.

I can now open new Viewports on both monitors. 😀
