How accurate is having the output window open in UI?

I have a couple of buttons in the bottom of my screen, and it all looks good in the device testing, but when the output is opened, everything starts to look misplaced and looks weird all around.

My question is should I adjust everything to look good when the output just to prevent any degraded experience for a select few people, or do I not need to worry about it?

I don’t understand, even if you have output open, it should not bring issues to your UI. Try scaling around your game window and see if the UI breaks at specific resolutions. Also, could you give a screenshot of how it looks?

The issue can be a problem if players use window mode to scale their ROBLOX window.
