react-native-bottom-tabs got slower from 4.16.x to 4.17.x

[ferrannp]

Description

If you install screens 4.16.0, https://github.com/callstackincubator/react-native-bottom-tabs works just fine. If you install 4.17.0 or above, switching tabs is slow (like blocking). See videos:

4.16.0:

4.16.0.mov

4.17.0

4.17.0.mov

Steps to reproduce

Install react-native-screens 4.17.x or above and use @bottom-tabs/react-navigation@0.12.x.

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

I was able to reproduce it by bumping to 4.17.x any clues what might cause this? @kkafar @kligarski

I found the source of the issue.

Looks like this PR introduced this regression: #3173 (cc: @kmichalikk)

Looks like this is called when switching tabs:

react-native-screens/ios/RNSScreen.mm

Line 798 in 3a588b1

newWindow.userInteractionEnabled = false;

Causing this delay when trying to quickly change tab.. Any ideas how to fix it? I guess it also affects your bottom tabs implementation

I also experience a random delay if trying to navigate quickly between screens in a stack.

@RohovDmytro could you provide a video?

Cause while we plan to research possibilities of not-turning-off interactivity for tabs, we do not plan touching the stack logic.

I have this issue too

Staying on 4.16 until there is a fix
