My primary monitor is 144hz while my secondary monitor is 60hz.
When I have only the primary monitor plugged in, this issue is not present.
When I have both monitors plugged in and an item on my taskbar starts flashing (such as when I receive a message on steam or WoW is minimized but something attacks me in-game) my primary monitor goes down to 60hz until I open the particular window to stop the flashing.
This issue has been present for months now and I'm not really sure where to start with trying to fix it.
Windows 10, GTX 1070ti, AMD Ryzen 5 2600.
Thanks :)
