Worked: never?

Short description of error

Wider distance allow to overlap color
closer distance between faces do not
closer distance between islands allow to overflow to neighbour island…

Exact steps for others to reproduce the error
open file, try to paint as seen in the video 2023-03-24_05-09-32.mp4

Thanks for the report. I can confirm.

Texture Painting in Sculpt mode (Experimental) behaves better here. It does not "leave" islands and does not have the artifacts show here on thin gaps.

See:

Note for 3d texturing, you tweak the bleed/seam margin on the Image (in the Image Editor)

(as opposed to toolsettings / options [3D view] for regular texture painting)

Not quite up-to-date about the status of this @Jeroen-Bakker or if a bleeding fix would ever see the light of day for regular texture painting?

If it isn't introduced recently I doubt that we want to spent time on fixing this specific case. The algorithm has been designed many years ago and hasn't been updated with the flexibility that current users want it to be. So there will always be some edge cases that doesn't work. Fixing this might introduce others along the way.

If someone is up for it and want to give it a try I welcome them. The new texture painting is related to the paint mode design and requires a developer implementing the design. In the near future I wouldn't be able to work on it due to other priorities.

So a known issue might be the best for now?

No, this has been around forever

The new texture painting is related to the paint mode design

So texture painting in sculptmode (experimental) will sort of never be moved out of experimental in its current form?

The texture painting part is fine. paint mode reimplements a workflow/UI around the tools. But as for users, it isn't likely that much work will be spent this year on texture painting and implementing the paint mode design.
