Hi,
Tool Linear Gradient: no repeat, color mode, antialiasing enabled, normal blending.
primary color - white - alpha is zero
secondary - white alpha - 100%
Original image:
Gradient from left to white. In the middle of image.
( I used Ctrl key in order to create horizontal gradient).
Looks fine, however, right part is not solid white.There are a lot of non white dots, especially in the right bottom. Pixels can be RGB(255,255,254) or even RGB(252,252,253).
I can imagine that 254 may be caused by rounding errors, but 252 is very strange.
Not sure how this tool works in 3.5, but I think it was fine. I quite often use Magic Wand with zero tolerance in order to select white areas and never had problems.
Now this tool does not work after gradient in my case.
In gimp this tool works as expected.
Thanks,
Alex
