Hello , I recently purchased the 757 however I have encountered an issue where my pfd, nd and fmc al flicker white steaks on the left of the screens, see attached picture for example (I tried to upload a gif / video with no success, the highlighted line continually disappears and reappears quickly)

I have tried a full reinstall and made sure windows defender and firewall were off. I do not use any 3rd party av that may interfere. This occurs regardless of the state of the screen , even in cold and dark.

Help appreciated!
