Fps can't be uncapped and shaders don't work

It keeps my fps at 60 and if I unlimited fps it will have mouse input delay( I tried this on 1.16.100 and my fps was above 60 and no input mouse delay lag) So I think its's because the render dragon update. Shaders don't work also in the latest updates but when I go to 1.16.100, shaders works, please fix this.( I edited this today so this is still in the latest updates)
