WebGL MultiTouch cause Application Slow

The Unity Editor Version is 2022.3.24f1 and 2022.3.47f1


Why does the touch event trigger ExecutePlayerLoop?
If multiple fingers are triggered simultaneously, it can lead to multiple calls to ExecutePlayerLoop within a single frame.
During testing on mobile, multi-touch can be very laggy


This is my exported Js Profiler from the mobile version.

Hey ctxunitygame,

Thanks for bringing this up, really appreciate all the information! This is a known bug, which you can monitor and vote or comment on here. Doing so really helps us understand user impact, aggregate information and prioritize work.

In the short term, if you don’t need mobile keyboard support for your game, disabling it should eliminate the behaviour you’re seeing. You can do so with the mobileKeyboardSupport toggle. This bug is pretty high priority though, and we’re actively looking into solutions right now that won’t require that workaround.
