Summary0002496: Moving/creating tempo/meter markers ardour seems to move markers randomly
DescriptionSometimes when moving or creating markers one or more are at different locations at one go.

Reproducable: Always

Steps to reproduce:
1. Create a new project
2. Create some tempo/meter markers

Sometimes it will happen that a marker is on a different location as the one I right-clicked.
Right clicking on the tempo-bar -> insert tempo change will open the marker dialog and there it is: The content of the position field is WRONG. If I enter the correct value manually the marker will be at the desired location.

I am running Arch Linux 2.6.27-Preempt and have a i686 Pentium M Processor.
I can't remember such problems on my gentoo box (but there I had a minor version of Ardour)
TagsNo tags attached.

A bug which sounds like this one can be triggered by creating a new session, scrolling the main editor window right and then adding a tempo marker; the tempo marker position in the new tempo dialogue is wrong.

This seems to be caused by line 1003 of The pixel_to_frame call on this line appears not to take into account scrollbar position. I think this can be fixed by changing line

popup_ruler_menu (leftmost_frame + pixel_to_frame(event->button.x), item_type);

but there's probably a more official way. There are other places in the code which call pixel_to_frame in a similar way and which should maybe be checked out.

Tested and attached a patch with the solution of cth103. It fixes the issue with the wrong position field content when CREATING markers. should solve the remaining problem occuring when MOVING markers.

the problem remains in current 2.0-ongoing.
creating new meters works ok, but dragging meter markers will confuse the timeline: after dragging, bar numbers are waaay off, and all subsequent tempo and meter markers are wrong.
workaround is to never drag but always remove/create meter markers.

this bug should be "major" (at least it is for people who actually use tempo maps).

hmm. looks like this ticket should be closed, as it's a duplicate of issue 0002377, which has more detailed reports.
