accidently got strange vertical zoom... (how to revert?)

Hello,

I know the standard horizontal and vertical zooming of the tracks.
But now I accidently used a keyboard shortcut and now all tracks look as if they were oversteered…
but its only the view that changed… but I don’t know how to undo that.
Does anybody know how to do that?

Hi and welcome,

On the right side of the Project window, above the Vertical scrollbar, there is a slider, where you can set the Waveform Zoom. Set it to minimum, please.
