I’m not sure, but the exact same thing happens to me when using a resolution of 11136x2000 (around 5.69 aspect ratio). I just wanted to add a detail since I haven’t managed to solve the problem, but I found that this image glitch starts to appear from pixel 8193 onward. I don’t think it’s a coincidence; it’s not typical 8K (7680x4320), but from a texture standpoint, it still aligns with a power of 2 (128, 256, 512, 1024…). Could it be that there’s a limitation in the engine that prevents it from handling resolutions larger than that size for performance reasons? After all, when rendering through the Movie Render Queue, you’re rendering the scene in real-time, which has to be done at a very high resolution… I don’t know; if anyone has any ideas, at this point, it’s more out of curiosity.
