graphics – Bizarre Viewport bug in Maya 2018

I can’t Google for this sort of thing because it’s a very difficult error to describe, so asking it here is my last resort. I have to use Autodesk Maya 2019 for the game I am working on, along with the legacy default viewport. I’m unable to use Viewport 2.0 because some of the graphics won’t properly display in that mode. (I also can’t use a different version of Maya in this scenario)

I am currently editing a wall (plane) in a larger area model. Here’s what my texture looks like:

I make a new Lambert material & load the texture as the file, and this happens:
The image is in black and white w/ some rainbow lines making it look holographic when moving around the camera, and the UVs seem to be sheared.

This isn’t the first time that this has happened before, but I don’t have any older screenshots. I know that for some reason this just likes to happen a lot with square/plane-like geometry (Don’t know if that has any relation to the bug though) This bug happens once in a while & I haven’t found any possible pattern on what exactly triggers this.

As a troubleshoot attempt, I try and remove the material, make a new lambert material w/ the same texture, the same problem. Remove the material (again), use a Phong material instead, the same problem. Opened up the texture in Photoshop, re-exported the png, the same problem. Exported the texture as a jpg, the same problem, rinse and repeat. Thus, I’m not really sure if I can determine the problem sourcing from either the texture or setting up as a material.

Oddly enough, this problem goes away when I switch to Viewport 2.0. I made a new plane & applied a new material with the texture,

Here’s what that looks like in the legacy default viewport:

Here’s what it looks like in viewport 2.0:
Viewport 2.0

Bottom line: Is there a name for this sort of distortion, bug, or artifact? And is there a way I can fix this without having to switch viewports or versions of Maya? I think the bug is possibly sourced from hardware rendering but I’m not 100% sure. I understand that this, of course, is the legacy viewport so problems can be expected to occur.

Yes, I’ve restarted Maya & my computer. I am using the most recent drivers for my graphics card.

Here are my technical specs:

  • GeForce RTX 2070
  • Intel i7-8700k @ 3.7 GHz
  • 32GB Ram
  • Windows 10
