Lasso tool residue when digital painting
Hello,
I have the following issue with the lasso tool.
Whenever I paint whithin a lasso tool selection it will paint slightly outside the edges of the selection. This always happens with the first color I use and even if I try to erase the whole thing this residue line will remain.
I have not been able to find a solution online, maybe because I´m not wording my problem properly so I´m using the images below.
If any of you know how to fix this it would be great.
Thank you very much in advance!
