Black Screen when using Fly-In Feature (5.1 beta)

[mr_cg]

When using new Fly-In Feature from 5.1 beta i only get black screen (no pano visible, only skin).
Problem exists with default and custom skins.
Tried with Firefox and MS Edge ... same problem.

When deactivating the Fly-In featue everything is ok.
How to fix this issue?

Hi,
This is probably the display driver, the rectilinear projection uses less driver function than say Stereographic.
If you have a driver control panel please set Pano2VR to have full power.
If not then please make sure your drivers are up to date.
