By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Arne 2021-08-17 15:15:19 CDT 
When saving a PNG image from Kolourpaint using the "Monochrome" or "256 Colour" options (including the dithered variants), the saved image is all black regardless of actual contents before saving. Only the option "24-bit Colour" works as expected.

To reproduce: 
* Open Kolourpaint
* Draw anything (or nothing at all, leaving the image white)
* Save image, select "PNG" format and "Monochrome" or "256 Colour" option
* Close Kolourpaint
* Open saved image (with Kolourpaint or another image viewer: the image is all black

Versions:
* Trinity R14.0.10
* Kolourpaint 1.4.8
