GNOME Bugzilla – Bug 750385
If an update contains Libreoffice Calc, the detail window grows
Last modified: 2015-06-04 23:13:57 UTC
Steps: 1. Choose to update 2. System reboots and updates 3. After the update, click the notification with info about the update 4. Click Libreoffice Calc for details 5. The details info window now grows and will stay that new size. I think this is because the description is so long for Libreoffice Calc. I would suggest to make the detailed info window as big as that description, or find a way to linebreak the description.
Thanks, fixed in https://git.gnome.org/browse/gnome-software/commit/?id=dfeb32b595bbee7c0048fde58f0c4ba7245f0a78
