Generative Remove resolution issue ( Lr Classic)

[bassinga]

Generative remove content seems correct but image generated on thin line removal is blurry / lacking resolution.  This is the case with all varaitions.

Source image is 40Mpx Fuji Xtrans file. Selection was about 2.5 width of the line ( smaller than the blurry area)

Reproduction : import 

Lightroom Classic v14.5.1

windows 11 10.0.26100

You could be tripping over two defects in Generative Remove:

- Its replacement patches are limited to 2048 x 2048 pixels, so if the selected area is larger than that, LR will upscale the patch, producing blurriness and mismatches in noise.  Try selecting shorter sections of the wire that are significantly less than 2048 pixels long. That produces a good result on your lower-resolution screenshot (which is only 1500 pixels wide).

- The new version of Generative Remove introduced in LR 14.5 has a nasty bug, sometimes changing parts of the image far outside the selection. 

Please attach here a full-resolution JPEG exported from the unedited photo, so we can determine the best workaround and, if necessary, provide another example for the bug report.

Sorry, I didn't know about the 2048 limit, selecting shorter sections of the wire definitely solves the issue.
Despite 7728x5152 raw fuji files, this was the first time I got the issue, you don't get a wire cross your whole camera frame so often.

About the bug changing things outside of selection that happened also here,  knowing about it is enought for this not to be an issue for my current edits.

Thanks a lot for the resolution and detailed information.
