Created attachment 178896 [details] here you can see the bad rendering of the icon (the fedora logo) STEPS TO REPRODUCE 1. choose a custom .svg file as icon in "configure application launcher" -> "general" -> "icon" OBSERVED RESULT icon is rendered badly. no anti-aliasing seems to be applied. EXPECTED RESULT the edges of the icon should be rendered smooth.

Created attachment 178897 [details] the .svg icon file
Looks fine to me at 175% scale, 200% scale, and 100% scale. Can you take a screen recording of yourself applying this icon in the way that makes it look bad?
Created attachment 178918 [details] applying the icon yes, of course. i noticed it at one time in the past few days. i am pretty sure the time i noticed it was the time it occured, as it bothers my visual sense of aesthetics very much. i have no scaling activated, so it's at 100%, but i tested it and it does look bad at 125% too. i have been using this exact file for over a year without any problems.
i think it is clearly visible in comparison to the kde-default and firefox logos that the fedora logo lacks antialiasing.
Created attachment 178919 [details] the icon rendered by dolphin when the icon-file preview is rendered by dolphin it looks flawless too.
Created attachment 178920 [details] the icon rendered by dolphin with better contrast again
Created attachment 178921 [details] another file that works
Created attachment 178922 [details] the working .svg icon file
deleting the cache (~/.cache/*) also didn't help. (of course rebooting doesn't either.)
Thanks for the screen recording. I genuinely have no idea why you're experiencing this problem. The SVG looks fine to me on my system and is well-formatted internally. Any chance you can re-test in a new clean user account? Does it happen there too?
