Lightroom classic: when in Develop mode, dark pictures show an overlay of different colors. Similar to the black clip on the histogram. I already try so many options, but nothing seems to fix it. When I open the image on Library, it shows the normal colors. Any idea what I am doing wrong?

Thank you!

It's probably due to garphics card driver. To help us dianose the issue, please provide a copy of your LrC 'System Info'. You can obtain this from the LrC Help>System Info menu item.

Note that there's a Copy button at the top right corner of the System Info dialog box. You should use this button to capture the contents, then use paste to insert into your next forum post.

This is almost certainly a bug in the graphics driver. You've got an 11-year-old graphics processor and a four-year-old version of Mac OS, and AMD last updated the driver for that GPU three years ago. So there's no way to get a bug-fixed driver.

Try setting Preferences > Performance > Use Graphics Processor to Off.
