Have some really high resolution images (30,000 x 23,756 sort of size) and the thumbnails take a while to generate usually, but they did generate, now they do not.
They get to some time limit and then turn black.
Is there a way to turn this new time limit off or extend it. ?
AFAIK there's only a time limit when generating folder thumbnails. I don't think how it works or the time limit has changed in years, either.
A zipped example image might help us see why it isn't getting a thumbnail.
1.26GB zipped - will send a link to crashdumps@gpsoft.com.au. The image is showing black in the standalone viewer as well.
also this message showed in log panel
(OneDrive context menu not showing in DO by the way, also file explorer is showing uploading symbol and DO is not - it is showing a tick, which I'm thinking means available on device)
Thanks for sending the example image.
The problem is that the uncompressed image data requires more than 2GB of memory, which it turns out makes various Windows bitmap APIs fail (even on a 64-bit machine, because Microsoft are incompetent). There isn't an easy fix for that, as it would probably require using a specialist image processing library like VIPS which is designed for huge images and processes things in tiles.
Converting it to 24-bit may help in some cases, but probably not all. (Since it has an alpha channel using up memory but I think it's all opaque and could be removed.)
