I’m a new user to Brave. I saw the issue of fuzzy/blurry text rendering has been reported before on here and github. I figured out a workaround for this, it seems to be related to the Windows Cleartype feature. Brave was blurring the font so much that it became unreadable at times.
So to fix it, all I did was disable Cleartype and then re-enabled it, so far it hasn’t blurred again. There is however still some heavy anti-aliasing causing the font to be very soft, it does not look bad, I personally just prefer sharp/crisp font. I hope this helps for those facing the same issue.
