P: Linear gradients now slowly rotate while resizing (Windows)

Steps to Recreate: 

 

  1.  Select a Fish Eye Image
  2.  Apply Lens Profile
  3.  Turn Distortion control to +100
  4.  Select a Linear Gradient and draw on the image (it is easy to see if you hold down shift to ensure horizontal)
  5.  With Mask selected, grab either the upper or lower handle and increase or decrease the size of the gradient area
  6.  Note: There is a subtle rotation of the gradient clockwise or counterclockwise depending upon the direction of the drag.
  7.  Note: the upper or lower boundary of the gradient becomes discontinuous

    Tested Win 10 (nVidia GTX 970 576.2 (5/19/2025)
    Make a linear gradient then resize it by a good amount. While you're doing so, you'll notice the whole gradient subtly starts to rotate. I don't think this happened before the recent LR update, but I could be wrong.

 

Running on Windows 11.

 

Editing to add info: This happens with all images when lens corrections are enabled with a profile selected, assuming the profile has distortion correction. If you want to really magnify the effects of this bug, select a profile for a super distorted lens (such as a fisheye). The rotation should be pretty damn obvious then, unless you're trying your absolute hardest to not see it. 

 

Even better, with a fisheye profile selected, simply moving the linear gradient without even resizing it will result in an obvious amount of movement, and rotating it will clearly show it not rotating about its center point, but rather around some other point altogether.

@Rikk Flohr: Photography I made some edits to my previous comment in case you didn't catch them.

@Rikk Flohr: Photography Thanks for looking into this. Some notes based on the steps you added and your comment:

 

  • It does not have to be a fisheye profile. I've tested and observed this with the most typical lens profiles. I suspect the more distortion correction that's being done, the more the effect is exaggerated.
  • Also worth noting for clarity that the actual image or lens used is completely irrelevant. All that matters is that you manually choose a suitable lens profile (one that applies enough distortion correction to reproduce the bug).
  • If you make the linear gradient really narrow and add it such that the center point is in one corner of the image, then drag the entire gradient to an ADJACENT corner, this seems to accentuate the rotation the most.
  • The rotations I've witnessed are well in excess of 1°, and the most rotation I've seen is closer to 45°.

I worked on this report for a while and was finally able to reproduce it on a 34-inch monitor with a Canon 15 MM F2.8 Fish Eye. 

Even then, the effect is less than 1°

I've logged a bug with the Lightroom Desktop team. 

Thank you for the report and the extra instructions.

As this issue has mysteriously separated itself from the other (unrelated) thread it was merged into weeks ago, are there any updates on this?

Hey, @Generous_view0D45. Welcome to the Lightroom Community. I'll move the post to Lightroom Ecosystem discussions for now.

 

I've tried to recreate this and couldn't get it to behave as reported. Also, please test and confirm if the issue appears with a specific file. Please share a video & screenshots of the workflow and the system info from Lightroom Help > System info > Copy and paste into a text document > Upload and attach here.

 

Thanks!

Respectfully, I would not be here if this was a one-off issue with a single file. 

To be clear, when I say slowly, I mean slowly. Unless you're looking closely, you're not going to notice unless you resize the gradient by most of the length of the photo.
