Resolved 07/17/2026 | Black Pixels along Right Edge with Wonder 3

[metahades1889]

I upscaled images to 1500 pixels on the longest side using all three intensities of Wonder 3: low, medium, and high. All three settings exhibit the same problems in several images I upscale. And yes, the input images are free of black borders before upscaling. I’ve attached an example, but all the outputs have the same problem.

output (with black border on the right):

That is a bug on some unusual scaling factor (e.g. 1.2x). We will figure it out. Please give a try with some scale factors like 2x first then you can resize it to any kind of resolution.
