There is a minor bug with the display of ruler tracks: when you have a ruler track, sometimes resizing the width of the track headers column (explicitly when it’s too narrow) can create an offset in the horizontal position of the ruler’s units as the ruler track sticks to the header when the other tracks and upper default ruler don’t, for example a bars+beats ruler track isn’t synced anymore with the time units in the upper lane.
Could you attach a screenshot, please?
What ruler type is set in the main ruler and the Ruler track, please? Bars & Beats, or Timecode, or something different? Do you mean resizing of the track list width? Is the Cursor position at the beginning of the project at the time? Or somewhere else? Or it doesn’t matter?
