TEXTUAL_SMOOTH_SCROLL doesn't disable the smooth effect

The bug

I'm finding a way to disable the smooth effect in a VerticalScroll container. The only way i see is setting up the var TEXTUAL_SMOOTH_SCROLL as descibed in here

I've tested two levels of assigning a value to the variable

1. Shell lvl

> TEXTUAL_SMOOTH_SCROLL=0 python mounter.py

or

> TEXTUAL_SMOOTH_SCROLL=0 textual run mounter.py

2. Python lvl

import os

os.environ['TEXTUAL_SMOOTH_SCROLL'] = '0'

Both cases scrolling is still smooth, but i would like to disable it.

I don't think smooth scrolling refers to what you think it does here. What do you mean re smooth scrolling, and what would you want to happen with it disabled?

Well, i mean scrolling in general, the effect of flowing text while i'm pressing pgup or pgdown and would like text to be paged as other pagers do

Setting TEXTUAL_ANIMATIONS=none will disable scrollbar animation. You can also set that on the app with self.app.animation_level = "none"

If you want it more finely grained, you can implement action_page_down and friends.
