Issues with video in Cubase pro 10 and Dorico pro 2

Hi all! I’m having issues with video in Cubase and Dorico where after a few seconds of playback the video begins to glitch and the only way to fix it is to either close and reopen the video window or readjust the size of the window - both are only temporary fixes before the glitching starts again. I don’t have this issue in any other application that works with video. I tried to update my graphics driver but after going through the installation process, I get a message saying the driver isn’t compatible with my OS, which is up to date. Any other ideas or solutions? Is this a wider problem or just with me? Thanks in advance!
