P: Graduated filter alignment issue

Grad filter loses alignment when dragged across image when using 'hand' icon. The alignment issue appears to increase if the 'hand' icon is grabbed off-center in the image. The alignment error appears to be in a small arc with the centre off the side moving according to where the handle is grabbed. I.e.; if the handle is grabbed in the center(ish) the misalignment is small, increasing as the grabbed position moves towards an edge of the image. The issue is inconsistent but repeatable.

    Correct answer Rikk Flohr_Photography
    The engineering team has let us know that this behavior is expected whenever a there is an interaction between warps (including lens profiles, manual distortion, Horizontal/Vertical sliders in the Transform panel, etc.) and local corrections.  Lightroom will always attempt to make a best fit on those local corrections but cannot make a perfect application on warped images.

    Update: same grad filter wobble is present for the 18-200 lens using LR CC2015.8 on my Windows 10 laptop,
    70-200 lens is unaffected.
     (I just have those two lenses in current catalog on the laptop, it is recently created with only 8 photos total)

    I am also able to replicate this.
    Also confirmed that disabling lens correction is a workaround for the 'wobble'.

    I initially could not replicate this but late last night I found that it is as you just asked: it seems that it only affects specific lens profiles? here are the Nikon ones I tested:
    70-200 2.8 G ED VRII - not affected
    24-70 2.8G ED - not affected
    18-200 f/3.5-5.6  grad filter wobbles with lens correction on
    35mm f/1.8 - grad filter wobbles with lens correction on
    50mm f/1.8 - not affected

    Using LR CC2015.10.1 on Win7

    Does it happen for all lenses or only a particular lens?

    Rikk,

    The 'wobble" affects the gradient but as you'll see from the previous post, lens correction is involved in the cause.

    Hi Eartho,

    Thanks for that suggestion... the issue is corrected when no lens correction is applied.

    Is there any lens correction or upright being applied to the images?

    I have asked an engineer to view your video. I am waiting for a response. 

    Do the actual gradients applied 'wobble' too or just the hinting lines?

    Hi Rikk,

    I tried the export on a single image and there was no alignment error. I guess that's not a comprehensive test but it's yet another pointer to some catalog related issue. So I guess the question is what now?

    I am not sure how to answer your question, Harvey.  If you take on image that exhibits the wonky Graduated Filter and export it as a catalog, does it behave correctly?

    Hi Rikk,

    It occurs on every image other than some very old and small jpgs.
