in the launcher Optifine version switch!
So that you can change launcher in settings between all Optifine versions because there is such a bug in Optifine that you do not see that you sprinted! http://prntscr.com/m0qzrp

The solution is not to be able to switch optifine versions but saying which version has the bug so it can be changed for all.

And make sure that you don't just have the specific particles for that disabled in optifine.

Maybe you used particles mod with a ratio of 0, hiding the particles?

I did not notice any problem with sprinting yet.

Oh and you can't use the image function for showing prntscr images, you need to link them instead: https://prnt.sc/m0qzrp
