Multiple tracks in Sample Editor visual bug

Hi,

when I open 2 audio tracks in a Sample Editor and move my cursor through that window, there is a buggy visual. It looks like the cursor is painting the whole waveform everywhere you move it. See the video: https://drive.google.com/open?id=1XKnZFw5W_kPXsOW-Nu8BxMjZjoOUvH5D

Steps to reproduce:

  1. Select 2 separate audio tracks and open them in a Sample Editor.
  2. Move the cursor over the opened waveforms in the Sample Editor.

I’ve noticed this in previous versions before 10.2, but didn’t bother with it, cuz I thought someone else would notice that too and report/solve it.

I want to add an obviously related graphical error of the Sample Editor (NU 10.2.1 on Windows 7 Prof. 64bit, using i7 3930 K, 32 GB RAM, Nvidia GTforce 640). It leaves “ghost waveforms” after a pull-down menu has covered the waveform display.

The animated GIF in the attachment gives an example.
