Performance Bug: Hearthstone stutters at a constant rate, when in Windowed mode (when "Fullscreen" is unchecked in the game)

Flickering Mouse

I have found a solution! Go to the location of Hearthstone exe, right click it and go to properties. Go to compatibility then click Change high DPI settings and check the box next to ‘Override high DPI scaling behavior’, click the drop box and click System and then apply. This worked for me but made the cursor smaller but im ok with that. This was with Windows 10. No more stutter and lag.

this worked for me
