Random monitor glitch on boot

Random monitor glitch on boot

I have a XPS 7590 4k OLED (i7-9750H - UHD 630).

Dual booting macos Mojave and Windows 10 with Clover 4979. By the way I've tried to update clover but no luck.

Everything works as expected beside on special occasion random problems on booting Mojave. But I guess that's normal.

My doubt for now is this weird screen glitch that happens before even arriving the clover, the DELL logo doesn't happear and the computer keeps going like this. I have to force restart. It happens sporadically.

Should I add the bios version?
