Problem summary

Artifacts are created when using Clone or Blur tools with multiple UDIMs of the same texture.

Customer reported version
mari.4.7v1

Customer reported platform
windows10

Steps to reproduce

1) Create a project with a model that has at least 2 patches (UDIMS).

2) Ensure the patches have identical textures in the UV layout.

3) Disable Patch 1002 and click Patch 1001 to focus it.

4) In the Orthographic view, use the Clone tool to clone parts of the 1001 UDIM patch.

Expected behavior
The cloned texture should appear identical and without artifacts.

Actual behavior
Artifacting/corruption is present on the cloned texture. This also occurs when using the Blur tool.

Workaround
Using the Clone/Blur tool on the 2nd patch (1002) does not have the issue occur.
