apologies, accidentally submitted this while trying to upload another
attachment--
I don't if I can attach the MRE image directly, so here's an external link (if
that's okay): https://gofile.io/d/ZsYQiK

Summary of this issue:
Specifically the COG variant of GeoTIFF image files load incorrectly in
KolourPaint, resulting in a different part of memory being read as the pixel
data.
I also observed a segfault when right-clicking with the color picker, but I
have unfortunately lost the backtrace. I can try to reproduce it again if it
helps.

To reproduce.
1. Try loading the image linked above
2. Observe the image is loaded as a row of 32 pixels which can be interpreted
as pointers if you take the byte color values of one band of each pixel (since
it's a grayscale image).
3. Compare to Okular or Krita which load the image fine.
