Delay (lag) between selecting a note and it being highlighted (and subsequent actions)
Since updating so MuseScore 2 I have observed a delay between clicking on a note and it being highlighted. Consequent actions, like moving the note are also delayed. The delay is quite short (less than a second) but does cause problems with composing, slowing down the workflow.
Upon clicking on a note the note sounds quite quickly but the highlighting is delayed. If I start MuseScore in debug mode I observe the note selection change being delayed. (In debug mode there is outline of what is selected.
I am running MuseScore 2.0.2 on Xubuntu 14.04 with QT5.3 on an Intel Atom 1.3GHz with 1GB RAM. I expereince same issue using PulseAudio or ALSA.
