Taskbar Flashing Randomly

Hey, I just noticed when I was playing on Beta last night that my Win10 taskbar will flash (on both main and 2nd display) randomly after I click something in game, doesn't seem to matter much what that is. I am playing windowed mode on a 1920x1080 144hz main display monitor. Running game as admin with Widows XP (Service Pack 2). Any and all advice would be appreciated.

Also, anyone been able to figure anything out with resolution in general or is that impossible until the new client comes?

Thanks in advance!

What do you mean resolution. r u talking screen size? If you are you can create a batch file that first changes the desktop resolution to a smaller one. (whatever you want) then launch the update app to launch game. As for the flashing. I would suggest you go to the compatibility mode options and start checking one box at a time until you see it stop. Switching theme to basic in win 7 usually fixes this and I think win 10 has something similar.
