Lightroom displays grey when zooming in on large file

[benobiwahn]

I've got a fairly large panorama that has been stitched with PTGui and exported as TIFF file (approx 250 MP). After importing it into LR it is visbile within the catalogue, everything seems normal.

When I zoom in though, LR stops displaying the photo and instead only shows the grey background. All buttons and panels around the "display portion" of Lightrrom are unaffected. It's the space where the picture should be displayed, which turns into solid background grey.

I refuse to believe it's a performance issue since im running on an i7 7700k, Geforce 1060 and 64GB.

What's the problem here?

Lightroom Classic currently only supports TIFF files up to 65,000 pixels, See this document for more information https://helpx.adobe.com/uk/lightroom-classic/help/supported-file-formats.html

Thanks for replying, but my image isn't anywhere near 65000 px on either of the sides so the problem must be somewhere else.

A 250 MP image (e.g. 20K x 12.5K pixels) will usually be smaller than the maximum size allowed by LR (512 MP, 65K pixels on a side). So I think it's more likely that Benobiwahn is tripping over this long-standing bug:

I have the same problem. It stopped working from one day to another. Didn't changed anything. Just imported a new pano. Also updating the version (from 8.? to the latest) didn't helped.

It's just the library, in develop module it works.

Have a look at the date: https://community.adobe.com/t5/lightroom-classic/can-t-zoom-in-on-large-stitched-panorama-lightroom-...

Wish LRTimelapse would run with other programs to, so I would can go away from Adobe. Already using Resolve and Affinity Photo/Designer, all are amazing. Next step is to test some Lightroom alternatives. Using LR with LRTimepalse for only timelapses is an option. But yeah, it looks like the time has come to move away from Adobe.

Oh and if you have to edit panos (like fixing the sky or the bottom), use Affinity Photo. Works so great with the live projection and it's really fast. Wont think back for the PS (wasted) time with all the problems.
