Where is this button that makes my document grey?

Hello guys,

I’m frequently activating unintentionally a modus that makes my background lightgrey. This color is not shown in the browser-preview. Every time I just close and reopen the file to get it away.

That greytone is normally white.

Where is this button?

Hi Oliver!

I know exactly what You mean - in my case it shows up when I drag & select in the Animation pane… doesn’t happen very often. The only way I can make it go away is an operation that requires some sort of screen refresh; only once have had to restart Hype to get rid of it.
