GUI stutter when zoomed in on multiple (8+) audio tracks

Test Steps:

  1. Create empty project
  2. Added 10 audio tracks/unique files
  3. Zoom to 1 bar visible or closer
  4. Press Play
    -> Result = As cursor passes over visible audio in timeline, cursor and meters lag/stutter

Other Notes:

  • Lag/stutter starts after having 8-10 tracks of unique audio simultaneously vertically visible at 1 bar resolution or smaller
  • Meter/GUI animation returns to normal after cursor passes visible section of zoomed audio
  • I have replicated this issue on multiple PC’s with similar, high-end specs
  • Issue does NOT occur when zoomed in on MIDI or other types of tracks
  • This issue persists after a clean install of Windows 10 (64) and all software

PC Specs:

Core i7 4790K @ 4GHz
512GB Samsung SSD
Nvidia GeForce 210
Audio Interace: Roland Super-UAS10

Any ideas are appreciated!

Yes this is a huge issue in C9.
