I can reproduce the behavior in 2.90.1, 2.91 and 2.92. This looks like a bug to me. I also can't see an obvious reason why painting on the mesh doesn't immediately have an effect, it seems that it takes quite a few tries from different angles to actually get it to paint.

Since I'm not deeply familiar with the paint tools I might be missing a known limitation, but for now I'm confirming this

@rjg the reason may be that zero island do not cover center of pixel for example. Because it shifted or too small, or because bias.
It looks like painting mode wasn`t tested with pixel-art well enough. Blender do not have 1px brush (1px radius is not 1px)

But such type of texturing (pixel perfect, face perfect) is popular for game-art.

Since the implementation of Paint Mode will replace Texture Paint mode I'll tag this as a known issue.
But it's good to keep in mind for further work on any pixel perfect drawing brushes with #96225
