The Main (frustrating) Difference:

In 3.0, the DX11 fullscreen game client would not minimize when moving the mouse cursor to a different monitor to perform other tasks. Moving the mouse cursor back and forth to another monitor and back to the monitor containing FFXIV was seamless (link)

In 3.1 moving the mouse cursor to another monitor to perform tasks does not minimize the fullscreen game client, similar to 3.0. However, moving the mouse cursor back to the monitor containing FFXIV and then clicking causes that monitor to refresh. It is not possible to move the mouse cursor back and forth to do tasks on a second monitor seamlessly.

I suspect that the game client is causing a VRAM flush upon cursor reactivation of the fullscreen game window. This is not desired behavior for multi-monitor users, as this causes a delay when attempting to switch back into the game after performing tasks on any auxiliary monitors. For me this delay is around 7 seconds.

At least 1 other person can confirm this issue (link).

One other difference I noticed:

In 3.0, if I wanted to move a window from the non-FFXIV monitor to the FFXIV monitor, it would cause the game to minimize to a windowed mode. In the windowed mode, the game would retain its fullscreen resolution (just in a smaller window), so the resolution would look very compressed inside a small window.

In 3.1, moving a window from the non-FFXIV monitor to the FFXIV monitor causes a monitor or driver refresh, after which FFXIV remains in fullscreen mode and the window that I just moved exists either above or underneath the FFXIV window. Basically I can have a window float on top of fullscreen FFXIV, and interact with that window without minimizing the game (although with some delay due to the refresh).

About the two differences:

The second difference between 3.0 and 3.1 is probably an improvement. However, I fear that the same change that allows windows to float on top of a fullscreen FFXIV instance may also be causing the monitor/driver refresh when I just want to click back into the game after browsing the web on a second monitor.

I suspect that both differences may be the result of an attempt to fix this bug (or at least the bugs may be related):
