Having CBF enabled sometimes causes jumps to Be slightly higher and longer

Basically CBF makes jumps randomly higher by about 1-8 blocks or so, with normal size cube, normal speed, classic mode


 (haven't tested anything else). Happens on android 60hz AND 120hz (slightly More frequently on 120hz), newest version of everything. 

Also happens with all other mods disables except CBF. I Have a video of it But i can't upload it rn
