Description
Not sure if this is a duplicate of other reported rendering issues:
To reproduce, set laststatus=2 and define nnoremap <c-e> <c-e><c-e>. Then, open a buffer long enough and type CTRL-E repeatedly. You should see that part of the status line scrolls with the buffer.
Without Core Text the issue does not occur.
I can reproduce it with MacVim 8.1.950 (155) in macOS 10.14.3.

Research direction
Start by reproducing the issue in MacVim 8.1.950 on macOS 10.14.3 with Core Text enabled, using set laststatus=2, the given CTRL-E mapping, and a sufficiently long buffer. Compare the behavior with Core Text disabled; done means the status line remains fixed while the buffer scrolls.
