--- Comment #6 from wktradew...@gmail.com --- I downloaded the kio-extra source, and took a peek. And fixed it. Uh, no idea how to submit the fix, but I have it. I will figure it out. In the mean time, it looks like when the thumbnail was being created, the quality of the thumbnailer (I assume the scaler) was being set to 0. Setting it to 100 resolves the issue, with no notable performance impact (at least, subjectively). This makes me feel silly. -- You are receiving this mail because: You are watching all bug changes.
