When you die the cursor is able to leave the window for maybe 1-2 seconds.
In this time you can click anything on your second screen.
Anything that is open: texteditor, browser, ...
So when I turn right while aiming I might move the cursor to the right screen - I only need to die so the cursor gets released by GW[1 or 2].
A click to fire might become a click in my browser and start a video on YouTube. (A very loud video. )
(I wrote a longer text with more information. But your forum wrote "access denied" and my text was gone.)

@Cid543Hi, do you play in Fullscreen Windowed mode? How many monitors do you have?
If you press Alt& Enter to toggle to Fullscreen or Windowed does this prevent the issue from occurring?
Thanks.
