The first version of Cubase 8 did this with the scissor tool. After the 8.0.35 update it changed over to the Timewarp tool. I can fill the entire edit window with these crazy little numbers, and they don’t go away until I change tools. Kinda makes the TW tool useless.
What is your screen resolution and what Windows 10 scaling level are you using? Has the problem only occurred with Windows 10? Do you have any compatibility settings enabled?
Yes! I have this exact same problem. Whenever I use the scissors tool it leaves trail of little black numbers all over the screen. It’s seriously impeding my workflow. So much so that I’m thinking about ditching Cubase altogether. I’m running Cubase 8 Pro on a PC running Windows 8. Graphics card is NVIDIA GeForce GT 705, all drivers are up to date.
