Logo with rendering artifacts in HiDPI mode
Looks like the same thing we see in Discover: https://bugs.kde.org/show_bug.cgi?id=388253 Turns out this is just what it looks when Qt tries to scale up a too-small image. Talk to the Arch folks and ask them to provide a larger image! from my report in Arch tracker "Not a packaging issue, we provide a SVG logo and the same happens with the Plasma logo if you remove ours." Maybe KInfoCenter needs to set AA_EnableHighDpiScaling? Mm, could be. Thanks for the clue, Christoph. That was part of it! The pixmap itself also had to be adjusted for the screen DPI. Here's a patch: https://phabricator.kde.org/D10357 Thanks for your persistence on this, Dr. Chapatin. Also, you might ask the Arch folks to provide a more square logo for KInfoCenter so the window doesn't have to be a zillion pixels wide to accommodate it!

Show high-resolution and vector logos properly in HighDPI mode Summary: Take the device pixel ratio into consideration when rendering the logo, so it looks nice in HighDPI mode. Test Plan: Tested in NDE Neon with the standard Plasma logo, which is an SVG.

Arch logo pixelated in kinfocenter 5.12.3
Phabricator link says "FIXED-IN 5.12.1".
However Arch logo is still pixelated in kinfocenter 5.12.3.
See screenshot.
`grep LogoPath /etc/xdg/kcm-about-distrorc` should print out a path. Can you open up the image at that path and verify that it's actually a scalable SVG image or a HiDPI raster image? Created attachment 111311 [details]

Looks alright here. Tried deleting the cache? Hi Antonio How can I delete the cache?
