P: Random white images when exporting or publishing

When I export a series of photos, some of them do not export and I just get a blank slide Will try to re export to another photo and then it will export but several others will not export that did export the first time.

Glad to see this has been picked up again. I have posted this issue a month ago and have suggested it is due to LR's parallel operation using multi core CPU.

As John has mentioned, the problem is more frequent if resizing is turned on during export. The blank image occurs every third image if I resize to 1000px, less frequent if I resize to 2000px.

My work around is to use a text based watermark for the time being, it seems this issue only occurs using a graphical based watermark.

In my configuration, the bug happens frequently even with small numbers of pics being exported. In my testing, exporting 8 pics at a time, 3 of 6 exports had at least one blank pic. Exporting 4 pics at a time, 3 of 6 exports had at least one blank pic. The rate at which the bug occurs most likely depends on the size of the pic, the format (raw or JPEG), hardware speed, etc.

I will give this a try, although I believe I have experienced this issue with under 10 images at a time as well but will need to test further.

Another workaround is to essentially export 50 images or so at a time. Much faster than using 1cpu. I havent had any white photos when watermarking as long as I export less than 100 at a time etc.

I tried to find a relevant thread on the LR discussion and all I found were questions with no answers so figured I would add my details, I saw a reference to this thread with a request to post your problem so I didn't get a chance to read all the comments just yet. I am glad Adobe is looking into this and will hoping come out with a patch soon. Assigning a single core to "solve" the problem for now is crippling but at least is a work around, completely defeats the purpose of having a computer built for multitasking within LR. I look forward to a real solution soon, thank you for providing feedback so quickly.

If you read up above your posting you'll see that many people have reported this problem and Adobe has been able to reproduce the issue so there's no need to go into so much detail.  A workaround may be to assign a single CPU to LR using Task Manager.  This reduces the parallel threads Export threads and reduces the likelihood of the problem.

This problem only began when LR6 was introduced, the white image with watermark seems to be more persistent when running multiple operations. For example when batch exporting images one without watermark and one with watermark at the same time, the one without works flawlessly but at the same time the export with the watermark contained approximately 15 images with the white image and watermark. The export of the images only contained a total of 127 images. A little background on my system: Windows 7-64bit, 64GB RAM, 3.47 XEON, Nvidia Quadro 6000. With that being said my system has more than enough resources to handle such a simple operation, that and we experienced no issues in our studio prior to LR6. This is quite frustrating and needs to garner more attention from Adobe as it is a serious bug and cripples studios with any sort of production environment. We have to go through and view 100% of the files before exporting to any online viewing system or burning any sort of backups. Within Windows the thumbnail appears fine while the full version when opened only then shows the problem at hand.

Great News Rikk ..............................glad we got there in the end ..............now comes the hard part ..........the fix 🙂

Nice! Good luck fixing it! 🙂
