Testcase: Option "SendCoreEvents" "off" in the xorg.conf, restart server, start xev. The mouse pointer doesn't move, but xev still registers core events.
Created attachment 29788 [details] [review] Dont send core events if the device hasn't been configured for it. This patch fixes the issue. Core events are only sent for devices that are configured as such (the default anyway). For all others, the master device isn't updated and events aren't routed through the master.
Fixed in a26fd1a6d61507b3e69a04d6f6c192a6ec363c5c, part of 1.6.4.
