Some application icons are not showing
Affected version
OS: Arch Linux
Shell version: 3.38.1, Xorg
Bug summary
Some applications have blank/missing icons.
Steps to reproduce
Open an affected application, such as ffplay or Minecraft. In ffplay's case, a generic icon would be shown in previous versions (it did in 3.36), but since 3.38, it does not show an icon at all.
