Hey guys !

After the latest update, I'm facing a rather annoying problem. After I do all my export settings and press EXPORT Button, LR seems to time out for a couple of minutes (and don't respond) until it starts the export. After that the export time is quick as usual !

LR Classic ver 12

MacOS Monterey 12,6

@Rikk Flohr: Photography(and others here too) try using the catalog, photos, export presets, and watermark presets from my test:

(I updated the catalog folder to contain the export presets as well.)

I just tested on a near-virgin Windows 11 / LR 12.0.1 and observed similar 2.7x slowth from shadows. So that's three installations observing a problem with shadows: My Mac OS 12.6.1, my Windows 11, and @ChanSkinner's Mac OS 13.0.

@ChanSkinner Thanks for recording the comparison. Is this a consistant behavior with and without watermark? Do you see the same delay even with a single image?

Do you use a png/jpg watermark? if so, could you share a sample watermark with us.

@ChanSkinner , I think you're tripping over a different problem than the original symptoms reported in this thread. After observing very poor export performance with your text watermark, I identified a severe performance bug with text shadows in watermarks that was introduced in LR 11.4 (when Use GPU For Export was introduced). In my tests, in LR 11.4 and later export slowed down by 3 - 5x when shadows were enabled, regardless of whether the GPU was enabled. This suggests the bug was introduced when export in LR 11.4 was significantly modified to optionally allow use of the GPU.

The detailed bug report is here:

https://community.adobe.com/t5/lightroom-classic-bugs/shadow-in-text-watermarks-slows-down-export-by-3x-or-more-only-since-lr-11-4/idi-p/13328926

The original symptoms reported in this thread that most of the others here are experiencing are different -- after clicking Export, LR is pausing 30 seconds or more without doing anything, and then export proceeds at the normal rate.

[Updated to include Windows 11 results and the export presets in the catalog folder]

Starting with LR 11.4 (which added GPU For Export), adding a shadow to a text watermark slows down export by 3x or more, regardless of whether GPU For Export is enabled or not. This strongly suggests that modifying export to use the GPU introduced a performance bug with text shadows.

I timed the export of 16 sample .cr3s from the Canon EOS R5 and R6 with all combinations of:

- LR 12.0.1, LR 11.4, and LR 11.3.1 on Mac OS 12.6.1, and LR 12.0.1 on Windows 11 (that has no GPU).

- Use GPU For Export, Use GPU For Image Processing, Use GPU Off.

- A text watermark with Shadows enabled and Shadows disabled.

The detailed results are below. With the GPU off in LR 11.4 and later, shadows slowed down export by 3x. With GPU For Export enabled, the slowth was even more at 4 - 5x, but my Macbook only has 4 GB of VRAM (half of the recommended minimum for that option), so that could be contributing to the worse performance relative to GPU Off.

You can download the test catalog and photos from here:

https://www.dropbox.com/s/hy5msbfw2ahr1b3/Watermark.2022.11.08.zip?dl=0

The catalog folder also contains the two watermark presets and two export presets referencing them, as well as mac-system-info.txt and win-system-info.txt.

Mac OS 12.6.1:

Windows 11:

Was that enough? Will you be able to fix this? I really hate going back and forth between version to prove that there is something wrong with your software.

There you go.

@devilla.mac Thank you for sharing the video. A few questions:

1. Does the slowness happen only with 'Export with previous' or even by export via export dialog box?

2. What kind of watermark do you use? Is it a Png/JPG/basic text?

3. If it is a png/jpg, what is the file size of the watermark you are using?

4. Are you exporting the image to a Harddrive/NAS/local storage?

Thanks!

@devilla.mac I tired exporting with a few watermarks both text and graphic, did not find slowness. A screengrab should help, you can upload the video on any file sharing service you prefer and share the link with me.

Ok, I think we are getting closer tahnks to a previous repply. If I export without a watermark it works normal. the issue is with the Watermark.

Where do you want me to send the video? @Venkatesh Penjuri

To 12 I mean...

This is another matter. what takes long in our case is the start of the export and not the export in it self.

Hello Rick, I would need to upgrade to 13 again. Can you give me an email to forward the video to?

Thanks.
