Destroyed image
GIMP version: 2.10.18
Operating System: Windows 10 64bit
Package: Installer from gimp.org
Description of the bug
I have 12 jpg images (3888x2592) open in 32 bit floating point precision. When i make some color adjustments one or more pictures are destroyed. This is not an optical problem and can not undo via ctrl-z. If the picture was saved it also looks like destroyed. When I only work on 5 images at the same time the problem is not present. I think this bug is related to #4754 (closed). My pc have 8GB ram and 244GB free disk space. Gimp was the only running application.
