Thank you for your bug report, I think that was reported before and specific to GNOME sessions ... do you get the issue under Unity?

Unity status is unknown, I only have Ubuntu Gnome installed.

This applies to any action in the menu, "Invert selection" "New Tab" and any other I tested.

This is causing the whole desktop to hang. I opened the system monitor to see if it was causing the processor to hang, upon using an item from the menu, the system monitor's "resources" screen froze for the entire time of the lag-nearly a minute as I recall). When the desktop was working again, you could see where the CPU's had been spiking one at a time to 100% then dropping as the next one spiked for entire history shown (mine is set at 60 seconds)

That seems to be GNOME specific, maybe something for the Ubuntu GNOME team to work on then...

Opened a bug against Ubuntu Gnome for this issue.

This is bug in gtk+ and is fixed by upstream commit:
https://git.gnome.org/browse/gtk+/commit/?id=64521345b9480cce790e0b299ffa20b44d9461ff

seb128, it is reproducible in unity too, but that button is not visible there by default.

Hello Biji, or anyone else affected,

Accepted gtk+3.0 into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gtk+3.0/3.18.9-1ubuntu3.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I'm confirming, that gtk+3.0 version 3.18.9-1ubuntu3.3 from xenial-proposed fixes nautilus (and GNOME-Desktop) freezing issue after clicking any action in the Nautilus menu button on the right (tested with "Invert selection", "New Tab", "Select All"). Tested in GNOME-flashback and GNOME Shell sessions.

adminas@K101:~$ dpkg -s libgtk-3-0 |grep Ver
Version: 3.18.9-1ubuntu3.3

I can confirm that this bug is fixed in gtk+3.0 version 3.18.9-1ubuntu3.3 from xenial-proposed. From my testing it affected each machine differently and thus was really hard to understand why freezing happened.

This bug was fixed in the package gtk+3.0 - 3.18.9-1ubuntu3.3

---------------
gtk+3.0 (3.18.9-1ubuntu3.3) xenial; urgency=medium

  * Backport upstream patch to fix lagging and visual issues in Nautilus
    (toggled-not-clicked.patch, LP: #1562002).
