MuseScore 2.0 Beta1 (ditto in Nightly, October 2) /Windows7

First reported on the French forum: http://musescore.org/fr/node/35156

1. Open default score

2. Open the Lines palette -> Drag and drop a Line (single Line) on the score

3.Double-click to edit its length and position

Result: everything is ok until this line does not exceed the vertical position.

Beyond that, it disappears.

This bug appeared between the commit , correct (August 22, 11:07 p.m.): https://github.com/musescore/MuseScore/pull/1201

and the commit, incorrect (August 23, 6:39 p.m.) : https://github.com/musescore/MuseScore/pull/1153

So, maybe here: https://github.com/musescore/MuseScore/pull/1205

or (?, less likely): https://github.com/musescore/MuseScore/commit/d16e51e433e3027a157765af7…

or others (?): a lot of activity this day of 23 August.

- You will notice that "before" that (in the correct Nightly), the default length of the line was very short.

And "after", it had the default length of the measure. Cause and effect?

Yes, good work again narrowing it down! Part of the fix for short pedal and other types of lines was to prevent them from being drawn "backwards" (if endpoint of line is to left of end of text) but obviously that shouldn't apply to simple lines as well. Should be an easy fix.

Regarding the ghost images on drag, you should see those for any text line where the line itself is not drawn because it would be shorter than the text but also for any diagonal line with text. In the latter case, you would also find difficulties selecting the textline. This is also fixed in the PR.
