Guild Wars 2

Since the update earlier, my task bar now is superimposed while in windowed fullscreen. It wasn’t like this before and gets annoying when you frequently move your mouse. Alt-tabbing doesn’t fix it too.

This is almost certainly a windows related issue, not a gw2 issue. Recent Windows updates made some changes to how they detect “windowed fullscreen” applications, and those caused the taskbar to show above the gw2 app — and a bunch of other games too.

The most common cause seems to be running any sort of addon, overlay, etc, that draws additional windows on top of the game.
