a bug in photoshop CC, use liquify (forward warp tool) to picture, I want to chang the brush size with (ALT+Mouse right button+slide Mouse), (brush size) will move the number, but (brush pressure) number also move to 50 49 48....together, It's no correct. and Move the brush size also not smooth in using.
First off this is not the proper place for Bug Reports, this is
Secondly whether this is a is probably debatable because, as far as i can tell, for this to happen you have to move the cursor vertically a bit.
That the »sensitivity« for this seems to have been changed compared to CS6 does make this an unwelcome occurence for me, too, though.
Be sure you are dragging only horizontally, not upwards or downwards. New versions of PS made changing size and not effecting pressure easier.
Dragging side to side changes brush size.
Up and down dragging changes brush pressure.
