Tool paint buck doesn't fill everything
Hello everyone,
I have a small problem with my tool paint buck (I think this is how you say it in english), it doesn't fill everything when I first do lines with a brush.
See exemple:

I tried multiple thing, inscreasing the tolerence, changing brushes, changing mode, but I can't get it to fill entierly the zone I want it to fill.
It's not something I can't go around, just doing the non-filled space by hand. But it's annoying nonetheless.
Does anyone have an idea ?
