Thanks! I think this is basically bug 1459187 (https://github.com/servo/webrender/issues/2715).

as far as i can tell bug 1459187 is about performance. This bug is about memory use.
Unless solving bug 1459187 also improves memory use, i wouldnt call it a duplicate.

Maybe un-dupe it, and put a see also?

Performance and memory are bad because there is too much unoptimized work.
