I have pc which is equipped with nVidia GT1030 and connected to 4K TV. I tried previous versions of Batocera and latest one with exactly the same issue - menu in EmulationStation GUI is blank, has no items and you can't do anything. Screen is being initiated as 2160p resolution, so native for my TV.
This happened also on built-in GPU (Intel 630) with DP->HDMI converter (capable of 4K 60Hz).
Is there anything what I can do to have menu displayed? Otherwise the system is not usable at all...
