Significant Play Delay with Polyphonic Tuplets 2.X->3.0
Musescore 3 (nightly build) chokes on simultaneous multiple tuplets when starting playback. In Muscscore 2, the attached polyrhythmic two-bar score starts within 1 second after hitting play on my system, whereas, in Musescore 3, it takes up to 5.
To reproduce the issue, load attached score, start play; compare start times in both Musesore 2.3 and 3. (I am assuming that the play delay is due to how Musescore 3 parses polyphonic tuplets as the score is only two bars long.)
I reported the bug, initially confirmed by Marc Sabatella, twice in the forums:
"Musescore 3 (alpha2) starts slower than Musescore 2 with polyrhythmic tuplets"
Resubmitting bug report: "Musescore 3 impractical to use due to start play delay."
