Cubase Pro 9.0.20 issue with editor midi note color

Situation: Using an iMac and Cubase 9.0.20

Scenario:

  1. create a track with midi data
  2. play the track in a loop
  3. open the inline editor
  4. open the full screen editor
  5. stay in the full screen editor to watch you track events while playing it.

Issue:
While playing the track you will see that at the cursor the midi events are coloured in a mix of black and red (mix of black and red if you
have chosen like me to color the midi events according to the velocity).
The midi events keeps the mixed colours while the track continues to be played.

Issue does not occur when the inline editor is closed.

Could not reproduce on my system. (Windows)
