It would be very surprising if we had completely broken this in the latest update. Is this what you got simply by clicking on a precursor chromatogram? Have you tried clicking the magnifying glass button to zoom out and then zoom back in again? I got something like this recently with Skyline 22.2, teaching diaPASEF data at the recent course in Dortmund. I was able to get what I want displayed by forcing some updates of this graph. I wasn't happy and made mental note to play with this more when I get home, but I am not sure what you are seeing is entirely new and I would be surprised if you cannot get this graph to show you anything at all.
Hope you find the issue less persistent than you fear. We will certainly take a closer look soon.
