CodeMirror (including the uses of it in Firefox DevTools) do this thing where they only populate the part of the DOM for the visible portion of the scrollable frame. However, with APZ this doesn't work so well because content can't really know what's visible. The end result is that the user sees a lot of "checkerboarding" which is actually a combination of APZ checkerboarding and CodeMirror checkerboarding. Bug 1232491 should help with this because it provides CodeMirror a way to find out what the displayport is, and they can fill that part in. See also bug 1243554 and bug 1239615 both of which mentioned this issue. CodeMirror has https://github.com/codemirror/CodeMirror/issues/3564 on file for this problem.

Given bug 1160601 comment 17 onwards, is this a dupe of bug 1160601?

I thought we were using bug 1160601 to specifically track making the gutter more APZ-friendly. If you want to use it as a general-purpose CodeMirror/APZ bug then sure, we can dupe. I think it might be better to leave them separate though since they are relatively independent issues with different fixes. In particular, we need to expose the displayport to content before this one can be tackled, whereas the other one is entirely on the CodeMirror side.
