Description Rich 2017-01-07 20:54:19 UTC 
When using Glade on the GNOME desktop and then switching the focus to a different application window the CPU usage for Glade spikes very high and stays high until focus returns to Glade.  When the Glade application window is focused its CPU usage returns to "normal".

System:

Linux magnum 4.8.15-300.fc25.x86_64 #1 SMP Thu Dec 15 23:10:23 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

GNOME Version 3.22.2
Comment 1 Rich 2017-01-07 21:18:25 UTC 
I am also seeing the Xorg process spike in CPU usage along with the CPU usage spike of Glade.
Comment 2 Rich 2017-01-08 02:15:05 UTC 
I have found that the high CPU usage for Glade and Xorg only happen if there are some widgets added to the workspace.  The condition does not occur when Glade is opened to an empty workspace and left empty.
Comment 3 Rich 2017-01-08 18:38:25 UTC 
Also, not seeing the issue on a system which is using wayland instead of X
Comment 4 oldtechaa 2017-02-09 14:21:03 UTC 
I can confirm this on Fedora 25 with Xfce on X11. I would question whether it only occurs when Glade lacks focus, however. My figures on an i3-530 are 98% Xorg usage and 12% Glade usage when lacking focus, 8% Glade usage when focused.
Comment 5 Pavlo Solntsev 2017-02-17 13:38:26 UTC 
Same thing on up-to-date debian testing. Some terminal output is here (bug #778643). Let me know what else I can do to help with this issue.

Thanks.
Comment 6 Lukas 2017-04-12 10:54:08 UTC 
No idea if this is the same bug, but I get the same behaviour (high CPU load from glade and X11) when adding a Stack with a StackSwitcher, even when Glade is focused.

I did some debugging, seems like something causes expose events to be emitted continuously.

Could it be related to https://bugzilla.gnome.org/show_bug.cgi?id=763624 ?

Thanks for pointing this out, indeed this has to be a duplicate.
