Photoshop CC 21 Brush Hardness issue
I've been having this issue where my brush hardness and opacity will slowly decline over time. Issue persists no matter what brush I use.
With default hard round brush for example, it starts off at 100% hardness & opacity, and a few minutes later I'll notice that it's gone down to 97% hardness. If I continue working with it, the opacity continues to decline. Same issue happens with my smudge brush - smudge strength will slowly decline from 100% strength to like 95% after a few minutes of using the brush. I've seen this setting "vary round brush hardness based on HUD vertical movement" - dunno if this is the cause, but the issue persists whether it's checked on or off. I've also tried completely resetting preferences and uninstalling/re-installing photoshop but the issue persists. Issue started around 2 months ago, and is persisting to this day.
As far as I know CC is up to date and so is my Windows 10
