Freeze when using Image->"Scale Image" after Image->Mode change
Environment/Versions
- GIMP version: 2.10.28 and earlier
- Package:
- Operating System: Windows 10
Description of the bug
I use GIMP a lot for scanning images and converting to pdf. If I scan the image, crop, convert to grayscale or 8bit color, then resize, Gimp always freezes up, "Window Not Responding". Sometimes permanently, sometimes it will finish but after many minutes or longer. Maybe it would always come back but I havent tried waiting for hours. If I resize before converting, it works perfectly. This has been happening for years, dont think it is any new bug.
Reproduction
Is the bug reproducible? Always
Reproduction steps:
- Create a scanned image in 32-bit RGB
- Convert color mode to grayscale or 8-bit indexed
- Resize image
…
Expected result: Image resized within a second or two.
Actual result: Freeze, window not responding. Can sometimes come back after a long time.
