When playing FFXIV my screen begins to flicker black and then back to the game rapidly until I finally lose a signal similar to this thread. This problem only happens when I am playing FFXIV and even if the game is displayed on my secondary screen, the primary monitor still has the flickering problem happens. The monitor is a 1440p@144hz monitor (and this issue was happening with a different 1440p@144hz monitor I tried to see if it was a monitor isuse and I've attached my config info below. I've triple checked that all my drivers are updated for my graphics card. I've attached a video recording of what the issue looks like in this youtube video as well as opening the OSD to see the settings
