P: desktop: Spherical panorama creation hangs

Hello all,

I'm
trying out the new Adobe Photoshop Lightroom, coming from Lightroom 6.
One of the features that is critical for me is the stitching of spherical panoramas. Lightroom 6 is decent, but often creates a visible seam or other smaller mistakes, and I hope that the latest Lightroom is better. Unfortunately, Lightroom CC seems to hang after a while. Creating the preview works fine. When actually rendering the full panorama it uses 100% CPU as expected, but later it reduces to 18% CPU, and a few minutes later it's down to no CPU usage at all. The user interface is still responsive, it's only the merging itself that hangs in limbo.


Has anyone experienced this? Is there a solution? I have unticked "use graphics processor" in the p, but it didn't change anything in the behaviour. The merging process just stops mid-way.

I'm stitching 26 DNG files shot by a DJI Mavic 2 Pro drone. Below you can see where the "Performing Merge" step hangs.

    Can you give any ETA of being able to give an indication of an ETA of the fix?

    We can reproduce the problem as you describe it, and we are looking into how to address it. Thanks!

    Good point -- Lightroom didn't have the ordering I expected. It's those: https://stack.stuvel.eu/s/DPqu8PQCyXIOo2S (7-12)

    Can you list the file names of the 6 that will not merge, just so I'm sure which ones are the 'last 6'?

    The DNG files are originals from the drone (DJI Mavic 2 Pro), nothing second-hand.

    Oops, I didn't see your 3+3 message before I posted my last one. Disregard 🙂

    Interesting. Almost as if there is a problem with one of the image files on disk that your Lightroom instance is using. I assume you got the 26 originals that you provided to us off the memory card? Or did you export them from Lightroom? If the former, maybe try re-importing the images from the card, for another data point.

    Splitting the last 6 into 3+3 does work, though. Strange.

    I made a mistake -- the last 6 photos don't stitch. It hangs there.
