Portenta H7 usbc video out example with LVGL, out of sync

Hardware Portenta Portenta H7

Hi
After installing the libraries lvgl + lv_examples by kisvegabor, hooking up the h7 via usbC hub, to an hdmi monitor, i'm getting the arduino logo (or anything else i'm drawing) rolling up, as if the vertical sync is not working properly.

i tried several monitors, hdmi cables, and usb hubs. It all came to the same result.

Does anyone else have this problem?
maybe my board is malfunctioning?

Thanks

The board has to be portenta H7 (M7 core)
And the Library has to be lvgl 7.11 no higher
