from a file
Product: kolourpaint
Version: 19.12
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general

Bulgarian flag - png format
SUMMARY
White color becomes transparent when importing image from a file on top of an
image with transparent background
STEPS TO REPRODUCE
1. Create an empty image with transparent background.
2. Download an image with white color in it or use the attached one (Bulgarian
flag).
3. Open the empty image with transp. background, then click "Edit" --> "Paste
from file..." and select the image with white color in it (or use the attached
one).
OBSERVED RESULT
When the new image is imported, you'll see ALL the white areas of the imported
image are gone missing and have turned into transparent areas.
EXPECTED RESULT
Importing an image from file on top of an image with transparent background
should not turn the white color into transparent one.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux: Arch 5.5.1
(available in About System)
KDE Plasma Version: 5.15 until latest (saw this problem for the first time in
5.15 but it was still happening in the latest plasma two weeks ago when I was
on KDE for a while)
KDE Frameworks Version: N/A
Qt Version: 5
ADDITIONAL INFORMATION
I made a video showing the problem in details (the link below), hopefully it
will be more helpful understanding the bug better than my steps to reproduce.
People using full KDE desktop (Linux group on Facebook) confirmed this bug is
happening with their kolourpaint as well, so I'm pretty sure the fact I'm using
Cinnamon right now has nothing to do with it.
