OpenLara in Raspberry Pi 4

I am using Lakka nightly 2019-09-02 on my Raspberry pi 4 4GB. PrBoom and TyrQuake work very well for me. But trying to make OpenLara work, after downloading the demo, i hear the sound of the shots but i don’t see the image, the screen is black. The video driver is in “gl” and the core has “Hardware Shared Context” activated. Any ideas to solve this?

Framerate 30fps and Internal resolution is 320x240.

With Lakka nightly 2019-09-11 the problem remains…
