This kind of issues require system information, at least DE version. How did you add those icons to your desktop, or were they created automatically?
im using gnome 3.28, and the icons were automatically created, but if i delete one and re-create it with steam the result is the same
Same on KDE Plasma desktop version 5.12.6. Blurry Windows app icons, presumably not sourced from the largest image resource in the .ico files.
For context: Warframe provides nice icon with the following images embedded:
$ icotool -l 230410/3b8ddd969a289cdf233fafe0a77ca70655b9b2e1.ico
--icon --index=1 --width=16 --height=16 --bit-depth=32 --palette-size=0
--icon --index=2 --width=32 --height=32 --bit-depth=32 --palette-size=0
--icon --index=3 --width=48 --height=48 --bit-depth=32 --palette-size=0
--icon --index=4 --width=64 --height=64 --bit-depth=32 --palette-size=0
--icon --index=5 --width=128 --height=128 --bit-depth=32 --palette-size=0
--icon --index=6 --width=256 --height=256 --bit-depth=32 --palette-size=0
while image above seems like upscaled 32x32 icon.
When creating a desktop entry, Steam unpacks embedded icons, converts them and places in XDG specified location (in my experience it does it correctly).
Anyone with Warframe installed (sorry, I am not installing Ubuntu and downloading 30GB just to test this) - can you create a desktop shortcut for Warframe (Library -> right click on Warframe -> Create desktop shortcut) and then check following locations:
~/.local/share/Steam/steam/games/ - does it contain Warframe icon? is it an .ico or .zip file?$ cp ~/Desktop/Warframe.desktop ~/.local/share/applications/?~/.local/share/icons/hicolor/256x256/apps/ - does it contain file steam_icon_230410.png being Warframe icon?$ gtk-update-icon-cache -t -v ~/.local/share/icons/hicolor/ fix the issue?Nothing extracted yet.
as can be seen in the image desktop icons of games run with proton are pixelated and blurry
this might be a steam client issue but since it only happens in proton games, i think it is better to report it here
