Immediately after the loader, the GUI is torn. After a while there appears a torn chunk of red towards the top of the screen.

I no longer use that type of notebook (with NVIDIA), and I don't expect to find an opportunity to test with the same hardware anywhere in the near future.
I do have tearing with UEFI (without CSM) with Radeon hardware in an EliteBook 8570p, but it's visually different from the 2016 photograph of the bug with NVIDIA.
