System Information
Operating system: win10
Graphics card: intel UHD

Blender Version
Broken: 2.83 but same in 2.81a
Worked: 2.79b

Short description of error
Hi,
texture bleeding during painting does not work on large models (apparently), I don't know what is the limit but with 4 millions tris the issue is here.
Reducing the mesh seems to solve the issue. It is not a solution of course but it can help to understand what appends,

Here some screenshots showing the problem:

Exact steps for others to reproduce the error

Create a single scene with an heavy object (subdivided sphere with splitted uv for example)
Paint on it.

or:

Open attached file
In the object try to paint on the line that delimits the edges of the uv islands

Even increasing the bleed to 8px that line doesn’t disappear

Hi,
thank you for the answer, sorry for the bad tag, no this issue is not related to an add-on (
To reproduce the problem, simply create a sphere for example, split its UV to produce islands, pack them, subdivide the sphere to get more than 4 millions triangles and begin to paint ... you should see the bleed problem (use contrasty colors for base and painting), if you look at the uv island limits in uv editor you should see that bleeding dos not work. You can also try with the attached file, it use a modifier to be lighter but the problem is visible.
Thanks.
Pascal
test_bleed.blend

PS : after some other tries the limit for which the problem appears is less than 2.3 millions tris

Thanks.

Hello, my last tests seem to show that the issue is fixed, thank you very much.
There is another little issue related to the texture panting, but I do not know if I have to begin another thread.
It concerns the lag observed in the beginning on the first painting action (it disappear further in the same stroke and reappear when you begin a new one) , this lag (a portion of second) prevents painting by little and quick brush strokes like in a real painting (I can try to post a video to show the phenomenon). This is less pronounced using a very fast graphic card but it never disappear completely, may be there is something to do with that in order to have a very pleasant painting feeling.
Thank you again for your work, have a pleasant journey
