On the Speedometer 3 subtest "React-Stockcharts-SVG", we spend 2.7x as much time as Chrome in paint-related C++ functions during the measured time.

Firefox: https://share.firefox.dev/44CGhdU 3673 samples
Chrome: https://share.firefox.dev/3R0lb6l 1345 samples

Matching Chrome's paint performance on this subtest would improve Firefox's score on this subtest by 2.7%.
