Minor improvements, poor stability

After quick look at MuseScore 3.0.1 I noticed few cosmetic improvements (layout, more accurate dynamics, articulation, better integrated playback panel etc.), but it has huge problems with stability: during playing large files (symphonic scores for instance) it freezes, or “jumps” between bars. Version 3.0.1 uses approx. same amount of Ram as 2.3.2 (up to 400.000 Kilobytes ), but 2.3.2 is stable. Why such hurry with new version? There was also no improvements with sounds, but that is another subject.
Those who use it, will probably continue to use MuseScore (even older versions), others will start to use some payable software in the near future.
