Public bug reported:
I am using the pre-release Ubuntu 20.04 (updated on 2020-04-20) with
Gnome and XWayland. I have a dual-screen setup with an additional
monitor above the main one. The exactly same setup used to work on
Ubuntu 19.10.
When the top monitor is connected, the results of the "Show
Applications" or Search functions are mostly hidden. It works correctly
when I disconnect the top monitor. See attached screenshots.
```
/org/gnome/mutter/experimental-features = ['scale-monitor-framebuffer']
```
```
