Processing times increase dramatically sometimes

Software ART
1

I’ve noticed that sometimes, when I’m editing an image, the processing time increases dramatically. It’s usually when I enable Dynamic Range Compression. Sometimes enabling it causes images to take 30 seconds to update, sometimes it has negligible effect.

Is there some way I can avoid this? Some know issue that causes it?

Seems like it’s this bug: Dynamic range compression is very slow except on certain zoom levels · Issue #7565 · RawTherapee/RawTherapee · GitHub

Do you have a sample image and precise steps to reproduce? I use DRC regularly and never noticed this slowdown. My ART is self compiled from latest sources on Fedora 43.
