Events completely blanked and cycle region suddenly black

Suddenly All part/events in the project window are hidden, see picture. The notes are there (in the editor) but they are hidden behind a brownish haze. I thought the last update would solve this , but instead now my cycle region is also completely hidden! It was purple. The picture says it all.

Now I must colorize all my trcks manualy to reveal the content of all parts. This should not be the way to solve this.

Is this for support or is there another option?


Whats your settings in the Preferences > EventDisplay > Smallest Track Height To Show Data? What happens if you Zoom In/Out Vertically and Horizontally?

Actually my expectation is, some preferences become corrupted. Could you try Cubase Safe Start Mode, please?
