Alt-Tab Error

Since apparently this was deemed "insufficient info" on the bug side, I'll ask again here as I am unable to post there.

"Lately I have been experiencing what seems to be a glitch where alt-tabbing causes the game to hiccup, forcing me to sometimes click the screen multiple times in order for it to properly run, otherwise it's as though I never alt-tabbed back to begin with. I can "fix" this somewhat by switching to borderless window mode, then back to full screen, though it happens again if I fully exit out of the game.

This error only happens with FFXIV, and only since the most recent patch. Prior to 3.1, I had no issues."

As of posting this now, I alt-tabbed, which shrunk the game to a square, but still kept it running, forcing a second alt-tab. Upon going back to the game, it froze, music stopped and it required me to click on the screen again. This process repeated several times until I forced the game into Borderless Window mode, then back to Fullscreen. If I log out now, everything above will happen again.

I do not know how else this can be explained, but would appreciate some actual assistance.
