Summary0009217: Segfault when moving a wave region using the middle mouse button and also clicking/releasing the left mouse button while moving
DescriptionHi.

A while ago I reported a similar bug: https://tracker.ardour.org/view.php?id=8529
It is fixed in KDE neon / Ubuntu 22.04 / Ardour 6.9, thanks for that!
However, I found a variant of it which again leads to a reproducible crash.
Steps To Reproduce- open a blank session, no plugins
- add 3 or more wave tracks
- record something into the 1st track
- click and hold middle mouse button on the recorded region
- drag region to the 2nd wave track
- now click and hold also the left mouse button
- drag region further down to the 3rd wave track
- the region starts to jump back to the first and then to the 2nd track, although the mouse pointer is now inside the 3rd.
- release the left mouse button
- release the middle mouse button => crash
Additional InformationThe Ardour version I'm using is 1:6.9.0+ds0-1build1

In my recording and cutting process I mostly use the middle mouse button to drag regions around, especially if I want to keep the positions of them. But sometimes, due to sloppiness, it happens to me that my finger slips off the mouse wheel and also presses the left mouse button.
TagsNo tags attached.

Confirmed, starting a new action while one is already in progress:
