If you have a panel on the top edge of the screen the Plasma Search bar will be partially covered by it. This only happens on Wayland, on a Xorg session the Plasma Search bar will appear right under the edge of the panel. How to reproduce: -Start a Plasma Wayland Session -Unlock the widgets -Right click on the default panel > Panel Options > Panel Settings -Move the cursor on the "Screen edge" box -While holding left click drag it to the top edge of your screen -Lock the widgets -click on an empty part of the desktop -start typing on your keyboard in order to make the Plasma search bar appear Imgur Album: https://imgur.com/a/INsIQRa
