I've been getting this bug for quite some time and I'm wondering if anyone else has experienced this at all. Basically the drum pane grid moves independently from the names on the left hand side when switching from track view to the PRV with the drum pane.

Here's an example of what I  mean (the 4 notes close together are actually kicks but don't line up till I scroll to the bottom)

 

I don't know if it's related but many of us are experiencing misalignment in the PRV ...

Hoping this is fixed soon as it's a royal pita!

The workaround for the PRV is to click the zoom buttons and it realigns. Tedious as it must be done every time he PRV is opened.

Can confirm that I have to hit the zoom button at times to get the PRV grid to align with the piano keys or drum map.

I have yet to see the PRV alignment problem myself, though a fair number of others have reported it.
 
That drum pane issue is a new one on me, but it could be related.
 
I'm wondering of either or both of these issues could be related to having a locked PRV in the project, something I seldom do.

Does the PRV alignment problem happen in the same way as the animation I posted above? I haven't noticed this in the PRV

No, with the Notes Pane issue you get a fixed offset between the keyboard at the left and the pitch rows:
 

 

Oh weird

Very strange indeed. never seen this before but like others I have heard complaints of the mis aligned prv and zoom seems to have some relation to it. sorry to hear of your troubles man.
