Monochrome display issue

I just decided to view my simple model in monochrome mode, and noticed that vertical faces (booth back wall and podium) with a textures applied (as a textures, not as images), are displaying with an odd a visual glitch. This appears in the modeling space and in 2D export. There is no z-fighting, but it looks similar. Any ideas?

Ragged shadow edges. Model far from origin?

I haven’t tried recently but it used to be possible to use an image as a texture by grouping it with some geometry and then sampling from it. This created a texture that didn’t show in the Materials browser but displayed in Hidden Line and Monochrome modes.

Nope, shadows seem clean and intact.

Nope, right on the origin.

Materials weren’t sampled and applied to anything else. This only shows up in monochrome, not in any other view mode.

Old or new graphics engine? I’m guessing if it shows up in export than it shows in both…

Update: issue resolved

The images used were PNGs exported from Adobe Illustrator with an alpha mask, even though there was no transparency. When I re-exported the images without any transparency mask, the issue went away. So, the issue happens when the texture has transparency, even if there is none (I know that sounds odd).

What happens if you switch Transparency quality to Better in your style settings? Genrally using transparent PNGs requires this to display right.

Good idea, but unfortunately doesn’t have any affect.

I feel like this is an issue though. Monochrome should strip all materials and leave just the solid faces as designed, and probably should not have visual glitches like this even if there is a transparent pixel at play.
