Channel switcher UI clean-up

Description

Looks like a regression, screenshot from community-release is attached.

Sudheer changed it for performance reasons I think, so we need to think whether we want to revert that change, or improve the UI based on how it is right now.

QA Test Steps

Should be fixed on daily.
