First person perspective bug(in android i think it only happens)

[Kitsuro]

In first person,I use the android version of srb2,there is a big where when I look up or down the entire levels stretches a lot for some reason.Is there any way to configure this or not?

It's the software renderer causing that.
Switch to OpenGL(options -> video -> renderer) to fix it

If i switch to openGL,My game will lag allot for some reason and the entire levels go invisible.

This is a "bug" in all versions of the game played under the Software renderer.
This is due to a funny trick to allow vertical aim. See: https://zdoom.org/wiki/Y-shearing
OpenGL does not have this issue as it performs true 3D projection.
