Lately I am having problems switching windows (window manager windows)
using Alt+Tab. Like exactly right now when I type this in Emacs I try
to switch window and it does not work. I can see the frame of other
windows being marked/outlined and in the task bar the name of the
window I am trying to switch to becomes bold. I have to use the mouse
to switch instead, very annoying.
Until today I have thought this being a glitch in Metacity but by
chance I stumbled upon the following messages in my .xsession-errors
file today:
Window manager warning: last_focus_time (5775062) is greater than
comparison timestamp (3763886959). This most likely represents a
buggy client sending inaccurate timestamps in messages such as
_NET_ACTIVE_WINDOW. Trying to work around...
Window manager warning: last_user_time (5775062) is greater than
comparison timestamp (3763886959). This most likely represents a
buggy client sending inaccurate timestamps in messages such as
_NET_ACTIVE_WINDOW. Trying to work around...
Window manager warning: 0x3c000a4 (.emacs) appears to be one of the
offending windows with a timestamp of 5775062. Working around...
It suddenly occurred to me that I only experience the switching
problem in Emacs and here is a reference to one of my Emacs
windows. Could it be a coincidence or is Emacs doing anything bad? I
don't want to report this as a bug just yet. Does anyone else have similar
experiences? I cannot say when it happens, it suddenly does. When I have
switched using the mouse it works again, for a while...
