Well i tried everything and i swear it wasnt like that in yesterday and 2 days before version cause i was doing a lot of brush6 images with pressure based size and opacity , not even had single stroke like this, now what i see is 3 levels of sudden fall of opacity when im doing my strokes, its definitely too harsh and too sudden, its like level 3,then 2 then 1 and then 0 opacity:

I dont know, i would like to get rid of these obvious changes in opacity, its repeating almost exactly on different strokes, its almost impossible for me to make it happen at will and adjust my pressure to get the same effect twice , not mentioning 4 times in a row with 0 effort to make it happen, just big size and fast strokes.
If im not using pressure based opacity on brush then strokes are nice, when im using opacity then its blobby again, i believe it should fade out more gradually instead of sudden drops like that.

-I think this might have something to do with it , it happens when im using blending setting in brush and have it over 10, it doesnt look like blending, maybe theres some bug somewhere in blending code of brush6 because other brushes blend normally :
