 Component:  ports   |    Version:
Resolution:          |   Keywords:  legacy-os
      Port:  qemu    |
---------------------+-----------------------
Changes (by Ionic):

 * Attachment "patch-ui-cocoa-legacy-os.diff" added.

 This seems to compile, but somehow doesn't work properly. I cannot input
 anything. Whenever I press a key, I just get an audio bell signal. Also, I
 cannot uncapture the mouse pointer once captured (well, naturally, because
 the keyboard input doesn't seem to be getting processed correctly).
