I haven't observed "display corruption",= but on my MacBookPro16,1 the bottom
and right edges of the TTY are not on the screen, so a few lines of text cannot be seen.

This also occurs on the internal displays of all (as far as I know) other 2018-2020 Intel Macbooks when using the Intel GPU (The 15" and 16"= ; ones
also have an AMDGPU, but this issue occurs when they have the Intel GPU
set as the boot gpu).

There's a similar patch that hasn't been sent upstream that people with the= se
Macbooks have been using:
