screenshot of the problem
The broken png has the md5sum of:
b3f2da02e0e05ddd876a7f928e57298a
This is a screenshot of what I get.
Also tried it in Gimp, Okular and Gnome Bildbetrachter ... only gwenview fails
This was a Qt5 PNG decoder bug where the decoder incorrectly read the inverse of the proper gamma value from images without an ICC profile present. Already fixed in 2021. Problem is gone in version 22.12.3 |
