--- Comment #7 from Aaron Wolf <wolft...@gmail.com> --- I found this shows up with png files that were processed with pngquant. The original file looks fine in gwenview. The processed file still looks fine in Firefox and in Okular, but it is glitchy in gwenview when zoomed in or out. Adding an attachment of the exact same pngquant-processed file zoomed in Okular and Gwenview, unprocessed PNG screenshot showing only Gwenview with the artifacts. -- You are receiving this mail because: You are watching all bug changes.
