New to this version, not in any previous version…
I have the default setting for “Upscale and Resize” set to make the longest edge 2048 pixels, if it is smaller than that.
If I drop a bunch of pictures in TPAI, and process them, the Queue display shows that all are resized, if smaller, but only the first is actually resized. All the other output files are the same size as the original, though they are given filenames that indicate that they have been resized. to 2048W or 2048H.
Don’t have time to look any deeper into this issue at this time. On quick examination, it’s not obvious that anything is changed between the input and output files, except for the first.
