Bug#900657: steam: Screen animations freezes the screen

[Vinicius Couto]

Package: steam
Version: 1.0.0.54-5
Severity: important

Dear Maintainer,

In the client, moving the mouse around the tabs (shop, library, community...) or clicking in the play or install game frequently freeze the screen.
Openning the game through the command line continue to show steam popup, but not communicate with the client.
kill -15 not work.
The only way is clossing using the kill -9 command.
