OK, I can reproduce this. But only with the PRV in the Multidock, and only if I open with a keyboard shortcut or "right-click / View / PRV". With the PRV window floating things work properly and if I double-click the clip to open the PRV it's also correct.
(display image only to make it bigger)
Things of note :
1. The now time is completely to the left, on the proper position on the time line, but it (and measure 5.5) should
be centered in the pane.
2. The velocity bars are correctly placed with respect to the now time (they're for the notes following the now time),
but the bars should be on the right side of the pane if the now time were in the middle.
3. The notes are too far to the right with respect to the now time. Completely after it instead of centered on it.
4. If I scroll with the scroll bar arrow buttons, the error is maintained and everything shifts. Scrolling with the scroll slider
immediately fixes the error.
I can reproduce repeatedly. If I use a keyboard shortcut I can open and close the multidock'ed prv and it's always wrong.
