Edit: I just noticed that the vertical line to the right of the icon is actually a part of the default 'white box' application icon underneath the pacman one.
If I move the window sideways, pacman lags a little and I can see the original icon appearing half underneath it.
You may want to look into reading the graphics settings to account for scaling issues, since it's quite likely that people using larger (or smaller!) than default titlebar fonts or window sizes could end up with weird resulting graphics...
