Lenovo Legion Y520 Laptop with dual video card doesn't draw main 3ds screen when started on Nvidia GPU

Issue:
Lenovo Legion Y520 Laptop with dual video card doesn’t draw main 3ds screen when started on Nvidia GPU (automatically or forced). Both Monster Hunter XX and Monster Hunter 4U don’t show the intro video, the characters in the character’s selection screen don’t show, after the games starts the video gets locked on load screen while audio and the emulated touch screen respond to input.
Runs without issues if run explicitly with Intel video card.

I did not find anything wrong in your log file. Please wait for a moderator to assist.

Try latest nightly build and see if the issue persists.

Nightly #866, identical behaviour.

Install the latest nvidia drivers and reboot your system.

After installing version 398.82 of the drivers, the problem disappeared.
Thanks.
