Hey thanks for your message.
No there isn’t a marker track in the project. Maybe I’ll try adding one and then removing it to see if that does anything… Cluching at straws here
Does this only happen on that specific Project or do other older ones exhibit that behavior?
If you create a new blank Project and then add a few Tracks do yo see the lines in that? If not, then try importing all the Tracks from the ‘broken’ Project & see if they bring lines in with them.
Sorry I don’t have an answer but I do have a similar issue, ie a 10.5 project I’ve been working on has a couple of orange vertical lines when I open in 11 (not when I open in 10.5), and I can’t work out what they are either - I haven’t used a marker track in the project. I would send a pic but am struggling to attach images to a post.
I had this with old projects that I opened in 11 and my default template project.
There were 3 vertical lines at bars 1, 9 and 11
I never use marker tracks but… After some poking around I added a new marker track and there markers at 1, 9 and 11. I deleted them and ghe lines were gone. Then I removed the marker track.
Seems I had some invisible markers on my default project template I’d been using for several years.
I can confirm this is solved by simply adding a Marker track and then clicking undo on the ‘add new track’ action. And all the vertical lines disappear.
