15.3.1 has a very annoying bug, whenever I open the directory containing the dng, it starts the ImageThumbnailExtension process, which takes up 300% of the CPU
Currently there is no way to solve it, I wonder if there is a way to prohibit this process from starting? Or kill it immediately after detecting the start of this process?

Anonymous6922 Apr 10, 2025Try the software apptamer, which can limit the cpu usage rate in the background. You can limit the background of the process you don't want 300% to less than 10% and try to see how the effect works?

Poster Apr 11, 2025@ Anonymous687 That's right, there was no 14 before @ Anonymous3633 I have already done this, but there is still this bug. Later, I found out that if there is dng in the download directory in docker, it will also trigger, and the Show icon preview option will be ignored.
