Details

(Whiteboard: [sp3])

Chrome is currently 2x faster at https://grandprixbench.netlify.app/?suites=React-Stockcharts on macOS compared to Firefox.

The biggest difference is in the "React-Stockcharts.Zoom the chart (sync)" subtest.

Firefox: https://share.firefox.dev/3J3SdOp (165ms on my machine)
Chrome: https://share.firefox.dev/3kKr49V (85ms on my machine)

This subtest consists of three animation frames / refresh ticks.

Firefox blocks in PWebGL::Msg_GetFrontBuffer for 33ms at the end of the first frame.

Chrome shows a gap between frame 2 and 3 but doesn't have any gap at the end of the first frame.
