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

Performance Bug: Hearthstone stutters, when in Windowed mode (when “Fullscreen” is unchecked in the game).

During gameplay, when a repeating animation is playing, you’ll notice stuttering at a constant rate. You can notice it quickly if you right-click a gold-animated card in your Hearthstone Library. It is especially noticeable when the system is under full CPU load (I run BOINC).

2560x1440 Fullscreen: No stuttering. Animation is very smooth.
1920x1080 Windowed: Stuttering. Animation stutters/hitches, about once every 600ms at a constant rate repeatedly, and looks terrible.

I tested these, but issue persists:

• turning off Hardware-accelerated GPU scheduling (HAGS)
• turning off Xbox Game Bar
• turning off Game Mode

Issue persists:

• Across drivers 432.00 to 460.79.
• When monitor is set to 60 Hz, as well as my default 144 Hz.
• On all Windows 10 channels – Release, Beta, and Dev.

Can you please reproduce the issue (test Full-screen smoothness versus Windowed stuttering, maybe on an AMD 3000-series CPU or newer, and more noticeable when CPU is under a little load)
… and can you please provide a fix?

Thanks,
Jacob

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
