GNOME Bugzilla – Bug 558723
Metacity prints warnings
Last modified: 2017-03-18 18:08:54 UTC
Metacity prints this message: Window manager warning: Attempt to perform window operation 26 on window none when operation 26 on none already in effect and others similar to it, whenever it does something and there is a grab in effect already. For example if you Alt-tab-tab-tab, the two last tabs will happen while a grab is already active. The problem is that these messages are logged in .xsession-error and therefore cause disk wakeups. See https://bugzilla.redhat.com/show_bug.cgi?id=467802 I'm patching out the warning in Fedora 10, but it may be better to make it a meta_topic() instead.
