Topic: Focus problem on Linux/Gnome/Ubuntu
This is present since 0.3.3 (i am on 0.4.2 now).
On Ubuntu Gutsy once in a while mouse would detach from the game, with the OS cursor reappearing.
A click would give back focus to the game, so that was annoying but nothing more.
I have recently upgraded to Ubuntu Hardy beta. The bug got quite worse, the game would get minimised in the application bar. Restoring it has no good effect, and the only way out is to kill the game's process.
While I really can't complain about the behaviour on a beta OS, the problem is anyway annoying on the stable (gutsy) version as well.
What would tipically make the game loose focus is someone messaging you with the IM Client. (So you can reproduce it quite easily with pidgin, asking someone to msg you). Beside of that, even after closing every other application does not resolve the problem.
Bug tested on with Compiz activated on Gutsy and with Compiz and Metacity on Hardy.
I'm running the linux32 binary.
Feel free to contact me for any additional info you may need.
Cheers,
