⚠️⚠️⚠️⚠️ Help mask

Hello everyone, I'm having problems with my version 4.0 in sculpting mode and in other addons too, but now I would like to know if anyone here could help me with how to solve this problem

Whenever I put the MULTIRESOLUTION modifier in sculpting mode to optimize the mesh and paint a mask, it keeps painting these squares, this doesn't affect the texture, I've checked it several times

This happens every time I put it in anchoring mode

which is when I paste a certain texture and scale and rotate it from the anchor point

My setup is a 3060 12gb 64gb mr
