I use Ubuntu 18.04 LTS, with GNOME desktop and Papirus icons pack.
When I click on the Show Applications launcher, everything is in order. But when I enter some text in the search box, the search results, are skewed to the right, instead of aligning to the center. See the screenshot below.
This makes it extremely difficult to make out what the results are.
Can someone suggest what the problem might be?
As UnKNOWn has suggested, this is probably an issue related to the GNOME Shell theme you are using. Changing the theme is expected to solve this problem.
In general, themes can cause unexpected issues, like the one you experienced. This is one of the reasons why some GNOME developers try to raise awareness against third party theming and ask distributions not to theme their apps.
Regarding users tinkering with themes, they mention:
If you like to tinker with your own system, that’s fine with us.
However, if you change things like stylesheets and icons, you should be aware that you’re in unsupported territory. Any issues you encounter should be reported to the theme developer, not the app developer.
