Hi and welcome to the forum,
This is not Cubase issue. Is the graphic card driver issue. It has been discussed here on the forum several times already. Please, search the forum for the solution.
Oh, I found the information… Please, try to follow this thread.
Or if you are using NVIDIA driver, try to install the driver the recommended way, please.
- Download the latest Studio driver version from here.
- Disconnect the computer from Internet to make sure Windows will not download and install own graphic driver.
- Uninstall the NVIDIA driver.
- Restart computer.
- Start the NVIDIA driver installation (as administrator).
- Don’t install the whole package, use the Custom (Advanced) settings.
- Disable everything (don’t install NVIDIA Experience, PhysX, etc.), keep just the video driver enabled.
- Connect your computer to the internet.
