Any scaling above 125% causes the mouse cursor to flicker. On my setup (TV connected to my PC) I need 300% scaling though. When playing on 4K.
Only workaround seems to custom scale below 150% in order to keep the cursor small.
Which makes text and cards blurry.
I believe the issue with the mouse cursor blinking has to do with system DPI to increase the size of font and items. Might be a limitation of the hearthstone client in working with DPI settings. Adding hearthstone to the list of exempt programs from the Operating systems DPI settings causes hearthstone text to become blurry though.
Ive posted in bug reports, technical support, other users have posted it from years ago and there is still no fix for it other than the above method which doesn’t work because cards become illegible
Is it possible to get a blue response to this? Just googling this issue will show others with the same problem.
