the green fill. idk how hard is it to fix, seems to be compute shader bug. (or maybe wrong parameter transfer)

This is weird since a fix (ee0e012 and 8cc856b) was made quite a long time ago. In addition, a PR servo/pathfinder#513 has been submitted to the original repo. A regression might have happend at some point.
