RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Martin 2014-01-10 15:06:46 UTC 
Version-Release number of selected component (if applicable):
RHEL-7.0-20140109.n.0

Steps to Reproduce: 
Go to Universal Access (System Settings -> Details)


 1. Enable Zoom
 2. Click on Options... near Zoom
 3. By clicking on "+" quickly increase magnification.



Actual results: 
Gnome Shell crash. "Something went wrong..." with logout button.
Crash again also on next login.

Expected results:
All of the changes you make should be noticeable instantaneously
Comment 1 Matthias Clasen 2014-01-13 18:49:23 UTC 
Did it crash because you changed it too quickly, or because the zoom factor ended up being too high for your hardware ? (if you can determine that)
Comment 2 Martin 2014-01-14 14:13:27 UTC 
I use HD3000 and I got Gnome Shell crash when I set magnification to 5x.

$ xrandr 
Screen 0: minimum 320 x 200, current 1600 x 900, maximum 8192 x 8192
LVDS1 connected 1600x900+0+180 (normal left inverted right x axis y axis) 309mm x 174mm
   1600x900       60.0*+   40.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  

When I connect second 1920x1080 monitor and use both side by side, I got crash around 2.5-2.75x magnification.
Comment 3 Michal Jaegermann 2014-01-15 20:25:51 UTC 
See bug 1053850 for Fedora 20.  There is possibly more information there although it does not appear to be exactly the same issue.  Seems to be related in any case.
Comment 4 RHEL Program Management 2014-03-22 06:15:36 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 8 Michal Domonkos 2015-05-12 11:04:56 UTC 
Fixed in GNOME-3.14.

(BTW, the original crash wasn't due to increasing the magnification too quickly; it would crash even when done slowly, in steps.)
