I am having a flickering issue after buying the Acer XG270HU for the FreeSync support. I am seeing random flickering every few seconds if the monitor runs at anything higher than 60hz (freesync on, crossfire disabled). I created a short video showing what is happening, if you click at 1:15 seconds you can see the flicker twice, just keep looping the video. Its not always in the same part of the screen and its really random but consistent. It does not happen when I set the display to 60hz, it starts happening (even on the desktop) if the display is set to 120hz or 144hz or freesync is dynamically changing it over 60hz. The first part of the video I zoom into show you that freesync is enabled noting the Hz changing with the fps of the game (Final Fantasy XIV A Realm Reborn).
