Yeah, I noticed that as well, but I don't think it's directly related to this
regression. Applying this patch on top of
78166b0b23a1c0ce81f19c7c85dc18a0d672425d gives essentially the same behaviour
as reverting that patch (for this application), including the shifted window
contents, etc. If that worked in 1.1.40 or before then that's an earlier,
separate regression.

Applying this patch on top of current git makes the initial contents visible,
but resizing is broken in a different way. I.e., you get the black screen and
error messages in the terminal. That's a later regression, and you'll have to
apply the patch for this bug while bisecting that one to track it down.
