Duplicate Connection build up #5658

I couldn't find a report on the same thing so I guess I'll make one.

A bug where connections build up, even when the connector is the same. So I end up with duplicate connections of the same knob.

Ctrl+drag a knob onto a automation track. If you drag the same knob again onto the same automation track, then it doesn't do anything. However, if you duplicate the automation track and ctrl+drag one to the other. Instead of doing nothing or overwriting, it adds it to the track.

I use Ctrl+drag to quickly change all those automation tracks to the one I want to save time, but instead it created this. Bug oh my gosh

Using LMMS 1.2.2

I can reproduce the problem by repeatedly CTRL-dragging an automation track onto another for the 1.2.2 Appimage. I do not know how you got to 794 connections above though. In the most recent master build the duplicate connections do not build up, so master does not seem to be affected. Could you please try to reproduce your problem with a current master build?

Also, to OP. Why on Earth you dragged automation patterns to each other?

master - not affected
1.2.2 - affected, and lmms hangs on 262128 active connections, which BTW consumed 2GB of RAM

Reproduced on master.

If you want to replace one automation clip with the pattern from another you can ctrl+drag clip to clip. That is faster than deleting one clip and copying another to the exact same position as the first. The same workflow is true for MIDI clips.
