Liquify_Utterly_Slow
SUMMARY
I was using a Krita Plus stable version. Check below for details.
The liquify brush engine seems not to be optimized/broken, I don't know.
Currently, while it's functional, it's utterly slow and stutters a lot in terms
of performance. Please, do something about it.
I have a core i7 3rd gen CPU and an Nvidia GT640M GPU and in Photoshop CC 2020
v21.1.3, the liquify tool is dozen times faster and smoother than in Krita.
