Cubase 9.5 Scroll spasms

Cubase Pro 9.5.10 Build 79, Win 10 Build 1709

Hi, In main window with Auto-scroll off, scrolling spasms (stutters/glitches) irregularly when pressing down the mouse scroll button and moving it horizontally.

  • Happens regardless if a track is being played or not.
  • Happens regardless of mouse tool selection.
  • As mentioned, It’s irregular, but does occur each session I try to scroll this way.

Never experienced this with previous Cubase versions including Pro 9.0
Anyone experiencing this?
