When using the old touch control, player cannot sneak at all even after spamming the sneak button. This only occurs to certain device which got higher refresh rate since this bug doesn't affect my Redmi 9 (60 fps), but it does affect my Poco X3 Pro (120 fps).

There is a way to "fix" this bug and also a way to "replicate" this bug (only if you have a mobile device that has 120 refresh rate or higher).

To replicate this bug:
1. Have 120 or higher refresh rate.
2. Go to options.txt and make sure (gfx_max_framerate=0).
Alternative:
1. Apply any resource pack that added frame rate slider.
2. Make sure the frame rate is set to at least 120 or above (default is unlimited).
