If you've come across an issue where Overwolf itself and apps installed in it look botched and grainy (check out some examples below), this is most likely due to a setting called "Hardware Acceleration".


This can be fixed very easily by disabling the Hardware Acceleration option in Overwolf. 

All you need to do is:

  1. Open Overwolf's Settings window


  2. Go to 'General'


  3. Toggle the 'Hardware Acceleration' option off


  4. Restart Overwolf in order for the change to take effect
