Oh, and also there was Exec=/usr/bin/steam %U at the beginning under the [Desktop Entry] section that I added your command to to make it look like this Exec=GDK_SCALE=2 /usr/bin/steam %U and it still didn’t work. Also, there are two steam apps, native and just plain steam in etc/usr/share/applications. I have two steams in my apps menu, steam(runtime) and native. It’s so damn confusing :/
