ViewportQT with two screens

[fabre.cedric]

Hello,

I have a small bug in my application with QT and I have noticed the same bug in the ViewportQT sample from Unigine 2.13 SDK.

When I run the application, my principal screen initialise the qt window with the 3D sample and my secondary screen display the video of "Unigine 2 engine of virtual worlds" and after my secondary screen stay black ?
I have this bug in my application when I set on a new viewport same size of my desktop windows size.

Thanks.

Hello,
My system is window 10 pro 64 bits with Nvidia Rtx2080S.
Resolution : 1920x1080 on the two monitors.
Same problem with OpenGl or DirectX.
Thanks

Unfortunately we were unable to reproduce this issue on similar configuration, could you please check that you're running latest GPU drivers and there's no additional software that could affect rendering, e.g. some recording or overclocking software, maybe some in-game overlays?

Maybe that was the trick, my principal screen in windows is the 2nd monitor ?

Tested with latest nvidia driver and same problem.

Thanks

Can you please record a small video with reproduction of this behavior?

Thank you

Hello,
I have tried with the windows capture tool but that doesn't work.

Do you know a free tool to capture the two screen in the same time ?

I guess you can use OBS for that: https://obsproject.com/
