So a few weeks ago I updated Windows 10, and since then whenever I switch to WoW from my second monitor (say, Google Chrome or whatever) the colours of WoW will invert for a split second. While mainly only annoying when it happens like above, if a toast notification comes up from Windows it happens frantically for a few seconds and is absolutely nausea inducing. This ONLY seems to happen with WoW. Overwatch and other games are fine. I run the game in Fullscreen (Windowed) mode. Switching to either Fullscreen or simply Windowed mode does not have the problem, but both of these modes have their own range of problems.

Please help.

I didn't find the right solution from the Internet.
