Any suggestion for sampling node or sampling for non-square textures

Hi guys.
It’s me again.
I am working on a configurator and the textures map gives me a challenge and I need to ask for some advice.
For my case, I need to work on the maps respecting to the real size and when I test my configurator, is where the problem comes out. Some weird noises come from the textures when I try to change the UV scales with the slider in real-time. The map is 1185 X 639 pixels.

Is there any way to avoid this noise(like setting up sampling node or boosting sampling size)? Or no solutions but apply square maps instead?
the texture sample shown in the playground:

This should do, you were having issues in your param setup


it solves my problem. Thanks a lot!!!
