Flicker when using non-square Flipbook Textures

[Kaffeebohnson]

There's a glitch happening when using non-power-of-2 (or non-square?) textures. In my case I use a 3x1 texture:

Somehow the flipbook texture displays pixel bleed (?) when further away. Note the texture border starts to "blink" when further away, even though the texture has no LODs:

I want to work with 3-frame animations, so sticking to square textures is not really feasible. Thank you for taking a look! Here's what you said on Discord:

There’s a chunk of manual LOD calculation code that needs to run for flipbooks. If your texture does not have lods generated, then it of course cant and won’t LOD your stuff, but there might be a small bug where this does the wrong thing with NPOT textures. The shader doesn’t actually know whether or not your textures have LODs
