langtable update? How could that influence gnome-shell?
I think langtable has nothing whatsoever to do with gnome-shell.

Are you sure it has anything to do with langtable?
How to reproduce it?

-> NEEDINFO.

What I know is that after an update which included langtable the gnome-shell broke, and when I downgraded langtable to 0.0.23-1.fc20 it returned to normal. Pretty convincing to me. I can try and iterate a couple of times again, but later today, I need my system right now.

Can it be a decimal separator related? Some of the gnome-shell glitches we related to the lack of scaling, some others to the lack of positional shifts of some elements relative to the global screen and each other, and I can imagine that it can be related to floats being treated like ints and hence be equaled to zeroes.

My locale is ru_RU.UTF-8 if it's related.

No problem visible for me.

langtable does have any information about number formatting.

And gnome-shell does not use langtable in Fedora 20.

→ WORKSFORME.

I reproduced it. In order to see the issue you need to install langtable not through "yum install" but with gnome-software's "reboot&install". When I updated langtable 0.0.24 with yum install I also didn't see any problems, but now I did it with "reboot&install" and it broke again.

distorted gnome-shell

The screenshot of the distorted gnome-shell. Notice absence of spacing between the icons in the dock and between workspaces on the right. Also notice the top-right menu, which is on the edge of the screen with some icons unscaled. Notice the partially visible icons from the bottom panel. The bottom panel itself is impossible to summon: the screen darkens, but the panel itself remains out of the screen. Notice how the windows stick together in the overview mode.

To fix this you just need to change "formats" in "region & language" back and again, and after session restart everything is back to normal.

langtable has nothing to do with these formats.

Change component to gnome-shell. Whatever cause this problem, it cannot be langtable.

This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
