ID 248385 - Colorspace flickering when copy and pasting patches

Problem summary
When copying a UDIM patch from one layer in channel to another layer in channel and different UDIM patches (from 1002 to 1003), there is a conflict in colorspace conversion and result. 

Customer reported version

3.1v2

Customer reported platform

n/a

Steps to reproduce

1) Open Mari 3.1v2

2) Open the attached archive. 

3) Change Shader view to 'view only the current paint/mask'

4) Switch to UV Patch mode

5) Select 'dif' channel, 'color_base' layer

6) Select UDIM patch 1002

7) Select patch 1003 (or multiple patch destinations for viewing the issue more)

8) Paste to selected patch(es)

9) Greatly zoom in and out to observe the colour swapping in a blocky manner.

10) Switch to Orthographic view and repeat step 9.

Note: This is also visible in some projects with checked boxes for raw and scalar data under 'color' and 'mask' but this is currently not reproducible.

Workaround
Unknown.

Expected behaviour
There should be no change in colorspace unless specified by the user.

Actual behaviour
There is conflict between colorspace conversions with patches appearing darker or incorrectly converted.
