When moving events

When moving events. Events strongly lagging behind the cursor. It interferes with work! This happened after the upgrade to 8,0,30.
Where it can be set up??
Thanks!!

Guillermo has said that graphics lagging with OR without video in project are under this issue report no.

Here’s a short video. It can be seen in cubase 8.5 events move with a delay. In Cubase7.5 does not.
It is not convenient to use. Someone tell me how to set it up?
Thank you!

And this has to do with the vertical and/or horizontal Line when working with tools and moving things around.

Turn these off in the preferences should bring improvement
