Description Dimitris 2016-07-06 18:52:12 UTC
Description of problem:

New after upgrading F23->F24:

Trying to grab a specific area of the screen puts g-s into a busy loop.  The copy/save dialog never appears.

Version-Release number of selected component (if applicable):

3.20.1-1.fc24

How reproducible:

Every time

Steps to Reproduce:
1. Windows/super key to overview mode, type "screenshot", select screenshot
2. Pick "Select area to grab"
3. Click on "Take Screenshot"
4. gnome-screenshot never responds, takes 100% of one core.

Actual results:

Spins the CPU

Expected results:

Should take a snapshot and present the save/copy to clipboard dialog.

Additional info:

Selecting "current window" responds with the next dialog after a short delay.
Selecting "whole screen" freezes the desktop for a while, but eventually responds with the dialog as well.

Unable to reproduce here. Can you install debuginfo packages for glib2, gtk3 and gnome-screenshot and then attach gdb to the process when it's burning CPU and get a few stack traces?

Comment 2 Dimitris 2016-07-08 01:38:00 UTC
Well, of course now I can't reproduce this.  I'll close and reopen if it happens again.

Comment 4 Rui Matos 2016-07-11 12:34:08 UTC
Ok, reproduced, see https://bugzilla.gnome.org/show_bug.cgi?id=768087#c2 for a fix, I'll close this downstream bug.

Comment 5 Sascha Zantis 2016-08-03 18:11:34 UTC
Sorry if this comment reopens the bug, but I still see this issue. Will this be updated soon?

Comment 6 Dimitris 2016-08-06 16:29:46 UTC
Sorry about yet another me-too: This is pretty bad - it's even locked up the desktop to the point where I couldn't ctrl-alt-Fn to the console to kill the screenshot process or ctrl-shift-del (does that even work any more?) - had to hard reboot.  Any idea when a build with the fix (backported?) might be happening?
