Rendering a colored plane with NO shading creates weird pixels at borders? I turn to you with a question about Blender (2.90) rendering behaviour.
I am rendering a colored plane only (literally, that's it - no shading, plugging the &quot;image texture&quot; node right into the surface node of material output), so quite a simple setup. However, when rendering the plane, Blender creates some weirdly colored pixels at some locations on the plane's borders (see image). Note that these are not visible in the viewport and only show after rendering.
I am rendering with Cycles, transparent RGBA, to 16bit png. I already tried setting Film -&gt; Pixel Filter -&gt; Gaussian to the smallest size possible (0.01px,  I need to render it without Anti-Aliasing), and also set &quot;Alpha Clip&quot; in the material section. I experimented with Eevee and also with different render resolutions (ranging from 250p to 1080p), alas to no avail. I tried setting the backside of the plane to another color, but that didn't help either. I also tried setting the number of samples in both viewport and renderer to 1, which didn't help either.

Does somebody have an idea what is going on here? Any hints appreciated!

Because you are using Repeat extrapolation in Image Node.
Those pixels are just texture's pixels from opposite side of texture.
Set Extend instead.
