Hi, I thought this got solved at one point, but now it's back and worse than ever. Posters flicker when you move and don't seem to settle down no matter your distance from them. A work around was to place a small beam or plank in the middle on the wall and attach the poster to that, but the small rectangle then flickers through the poseter (and it isn't really always possible to do it anyway).
Also related, I have placed "wood paneling" (planks) against a block wall (where I want a color on one side but not the thickness of two blocks (which is ridiculous). The paneling also flickers same as posters. My plan to "tile" my white floors that need to be white for the ceilings of rooms below won't work either.
Possible to fix the flickering?
Here's static pictures. Poster/planks flickers in geometric shapes.
