|Summary||0006254: Shuttle speed control has massive lags|
Linux Mint 17, 64 bit
When scrolling with the shuttle speed control it is extremely laggy. Strangely this only seems to happen, if a MIDI track is present in the session. See attached video for clarification.
- Open new session
- Add MIDI track
- Scroll with shuttle speed control
Always reproducible with my current setting but I don't know of someone else experiencing this issue.

||This is still present in 5.8. Still, only after having added a MIDI track.|
It depends a lot on the buffersize. Speed-changes happen once per process-cycle.
Particularly mouse-wheel'ing on the shuttle can queue a lot of GUI events which are processed at a lower rate if the buffersize is not small.
Indeed, if I decrease the buffer size a lot then this behavior is gone.
I'm not familiar with this part of the code base of Ardour. Would it be possible to drop certain GUI events if we know that they will become obsolete because of a later event in the queue?
Just to also make this clear: I don't care about the shuttle control because I would never use it productively in any way. I just think that if it exists, it shouldn't be buggy.
