I created a .desktop file for the "exploTux" game (see https://gna.org/projects/explotux/ ), but the launcher does not match the app window.
To be clear: when I click the launcher on the Unity panel, the game launches and work fine but the game window is represented by a new "launcher" in the panel.
Here is a screenshot:
The upper launcher is my .desktop, the other is the one that appears when the game is running (note that there is only one opened window and that the panel icon show 3 arrows as in "3 open windows"...).
I tried to pin this new launcher but then it makes unity crashy.
Where do you think the problem is? I tested on both Natty and Oneiric.
Here is the code of my .desktop file:
[Desktop Entry] Version=1.0 Name=exploTux Comment=A Bomberman like in 3D Exec=/usr/games/exploTux Icon=explotux Terminal=false Type=Application Categories=Game;ActionGame;
edit: I have a similar problem in Gnome-Shell:
