Whenever i play any server and use any potion... controls resets.
The main problem i found out that red area extends in server causes control to reset.
So i request minecraft to fix this issue by making red area usable for customize controls
There is also a problem in this that...if we use potion and then press jump it will open the potion status screen. Potion status bar should be somewhere else like on top corner or vertical like before 1.18.
I think i said too much in one complain
Pls try to understand what i am trying to say.
1 . Remove red region area in customizable controls.
2. Shift potion status bar to somewhere else or make it arrange in vertical alignment like before.
There are images of red region area in normal world(496kb) and in server after using potion effect(263kb).

There is a old pic(1.09mb) of player fighting wither in old version using potion..i think that vertical potion status alignment is better for phone players.
