Hello fellow playbackers

On my neverending search why Denemo has so worse playback performance I did a 
long test run this evening:

Internal Synth with all audio drivers (except Pulse!), Jack, all combinations 
of different latencies and samplerates and even a .sf2 soundfont with only 1 
MB, which is 9 times less than our current one :)
As expected nothing changed at all. 
I tested out different ways of giving midi infos (staff properties, midi 
directives, non at all, tempo slider etc. etc.). No change here, too.

And then I deactivated score view. Tadaa! Playback suddenly works as expected. 
We do nothing crazy in Denemo with an 8 MB soundfont, no effects and my 10 
channels in the test file. It should be able to work with a multiple factor of 
these values.

So something is fundamentally wrong in the playback/visual part.
