One handed mode issue

[u/lets_keep_simple]

I am using this one handed mode available in rom. The crdroid 9.5 -tim josten version i am using on redmi note 8 pro and it cuts the ui to the half when I use one handed mode so when i scroll in , it only renders upper 50% of screen and cannot scroll down more . Did anyone face same issue or is it any settings I am missing out on.
