Be wary of setting Application.targetFrameRate on WebGL, as it causes other issues:

rendering without using requestAnimationFrame for the main loop?

Hi there, We made a webgl build using 5.3.0, and we are getting this error when our game loads up. It doesn’t crash our game, but our frame rate definitely is lowered. Looks like you are rendering without using requestAnimationFrame for the main loop. You should use 0 for the frame rate in emscripten_set_main_loop in order to use requestAnimationFrame, as that can greatly improve your frame rates! Anyone has a clue as to how to fix this? Thank you.
