Cubase 9.5 & 9.5.10 choppy and sluggish GUI

When i turn on the Mix Console on my second display, the whole GUI is slowed down, choppy and sluggish, impossible to work with.

Also when i import video file, first few seconds of the extracted wave file are messed up. I did menage to fix this by replacing the “videoengine.dll” from the Cubase 9.0.3 version.

Btw, i have none of these problems with Cubase 9.0.3 version which is installed on the same computer.

Windows 10 (with last update)
Nvidia 1060 (with last driver update)

I have the same problem.
