## Observation

openQA test in scenario opensuse-Tumbleweed-DVD-x86_64-yast2_gui@64bit fails in
[yast2_lang](https://openqa.opensuse.org/tests/1114514/modules/yast2_lang/steps/13)

The window title is not centered, and also in the GNOME TopBar, the window name
is indicating that it continues with a lot of spaces behind the actual name


## Test suite description
Maintainer: zluo, riafarov

Test for yast2 UI, GUI only. Running on created gnome images which provides
both text console for ncurses UI tests as well as the gnome environment for the
GUI tests.

Temporarily added YAST2_GUI_TERMINATE_PREVIOUS_INSTANCES to see if helps. This
variable triggers code which terminates all yast2 processes before starting new
one. (see poo#26104).


## Reproducible

Fails since (at least) Build
[20191211](https://openqa.opensuse.org/tests/1111241)


## Expected result

Last good: [20191210](https://openqa.opensuse.org/tests/1109911) (or more
recent)
