Since 1.19 was released I had a bad experience in terms of sensitivity. When trying to look around on mobile devices I realized the sensitivity doesn't feel very smooth unlike the older version, this is very frustrating for me since I'm a pvp main and couldn't play very well while playing on the newest version. I hope this will finally going to get resolved soon as I have been waiting for this issue to be fixed for a very long time. 

Video comparison between 1.18 & 1.19

• idk if you can see the difference or not but if you look real closely you could see theres a bit of delay in 1.19 compared to 1.18

1.18 (with texture pack)
