When sharpeing B&W Images in PS, colours errors appear

[bena58748468]

Can anyone help!!

I'm having issues with some images - The image edits fine using my normal B&W preset in Lightroom Classic (All up to date), and exports fine so the RAW files seem to be ok, but when I sharpen them (in my normal way in PS, using a preset I've always used for years), these coloured errors come up on some of the images. It only seems to happen on B&W images though, and not all of them.....

I've tried re-exporting the problem images and then sharpening them again, and the same thing happens.

Any ideas what's going wrong?

I think you may be in the wrong forum.

this is premiere forum.

although try the default troubleshooting of exporting to a different image format, re-import and try again.

or clip colors from 32bpc to 16bpc, and desaturate to 0% color,  before sharpening.

@bena58748468 – Have you tried resetting preferences?

This could possibly be a graphics processor related issue.

First thing to try is Preferences > Performance > Graphics Processor Settings > Advanced Settings: untick GPU compositing if it is active

You may need to experiment with disabling/enabling other GPU settings or as a last resort turning off the graphics processor to see if this fixes the issue.

Finally, it may also be a similar issue to here:

Good luck and please let the forum know if and how this is resolved...

P.S. apart from habit of sharpening in Ps, you could sharpen in Lr.
