Hello,

Using v0.2.0 build on Ubuntu with realesrgan-x4plus weights and see the following result

Why the tiles are merging the wrong way?

This happens with JPG upscaling to -f PNG. If its -f JPG then it went ok

This happens because you are using a model only designed for 4x scaling. Scale the image down to the size you want
