Key editor display fails to update when editing midi notes using keyboard/mouse

Apologies if this has been addressed elsewhere. When I use the mouse/keyboard to edit an existing midi part in the key editor, my edit does not display immediately, but needs me to unselect the edit before the display updates and reflects the intended pick position or other edit. This is an issue and very time consuming. Has anyone else had this problem?
I have the latest update and there are no other significant problems. Thank you!

Hi,

Could you try in Nuendo Safe Start Mode, please?
