Weird trail behind player / entity when deferred graphics shaders are turned on

( excuse my english if its not understandble)

I have this weird bug when a player or entity walks when deferred graphics ( shaders ) are turned on. there is some kind of trail following it. I only have this on my phone because i tried it on my laptop and i didnt have it there (i have a galaxy s21 FE.) on the video my settings are on the lowest so there is no lag but this also happens on ultra settings. Why does this happen?
