Lightroom classic export not working since update

[eveblack]

Hello,

Since the recent update, I can not export images without them being color-distorted.  Does anybody know how to fix this?

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut out as that is just so much dead space to us non-Techs and it takes up vast amounts of scroll space making the reply less readable and less likely that others will bother with your post. Also large amounts of text in a post also render the Translate function inoperable.

Also, if you have a MAC, does it have an AMD GPU?

Many related issues on that, try turning off Use GPU in /preferences/performance/

Thank you,

I just got the issue resolved with Adobe's tech support. Apparently, I have to switch of the GPU ( which is an Intel AMD ) to be able to export now. I don't understand why, but it works 😉

Seems like its time to buy a new laptop...

Thank you for trying to help!

I would guess that as suggested you are on a intel Mac with an AMD graphics card. Ever since a recent mac OS update, the GPU driver for these cards has been misbehaving leading to ugly artefacts in Lightroom when using the GPU. Turning it off avoids this but obviously gives lower performance. You migt be able to get away with just turning it off for export if in the GPU dialog in preferences you select custom and deselect "use GPU for export" instead of turning it off completely. So you might be able to keep some acceleration in the interface.

I just changed my settings according to your instructions. I am on a 2019 Macbook Pro with an AMD Radeon Pro 5500M 8GB. and Intel UHD Graphics 630 1536MB.  Since I don't understand my specs, does this sound like I will need a new laptop soon to work with AI features in Lightroom, Photoshop, and Premiere Pro? Thank you so much for your help!
