This sounds more like a hardware issue than software on first glance. I would recommend checking all hardware connections within your PC and ensure they are tight and secure.
After this, check and update all drivers including those with your GPU.
To be on the safe side I would then recommend running a check and repair.
If the issue persists beyond this and does not occur with any other game/application, please submit a ticket including a WGCheck for our technical engineers to review.
