Delebot, thank you for the reply!

You mentioned that this issue started concurring after you reinstalled Windows. Could you try disabling the "Full Screen Optimizations"? Please do this by locating the "ffxiv_dx11exe" and right click and then select " Properties". Under the compatibility tab, please click " Disable Full Screen Optimizations." Once it is clicked, please select " Apply".

Please keep us update and hope to see you online!
