The application icon is lacking for HL1 (Probably also for CS but i don't own that game).
So the DE will just show the default icon for windows lacking one in both the titlebar and the taskbar.

It was tested on both gnome 2 and lxde (by zer0def).
The files were verified again before doing the report.
