The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/258527ddc93825a5feac1bd3de5f5efb8d975856

commit 258527ddc93825a5feac1bd3de5f5efb8d975856
Author: guidou <guidou@chromium.org>
Date: Fri Apr 07 16:00:45 2017

Update constraints algorithm for video content capture.

1. Update default from 640x480 to 2880x1800. The goal is to use the native
screen resolution as default, but this is an improvement over the current
situation.
2. If a maximum resolution constraint is given, use that as default instead
of the hardcoded default. This makes the algorithm more compatible with
existing applications without breaking compatibility with the spec.

rbasuvula@: r463309 contains another patch that fixes other possible cases of black patches. 59.0.3068.1 (463474) has that patch, but 59.0.3067.6 (463157) does not.
Try with 3068 on Windows when it becomes available. I believe it will be fixed there.
