I upgraded to 19.10 yesterday. Now, when I hit `Super` and start typing the name of a bit of software, no results are coming up in the search results area below the search box. But if I know the exact name of what I'm trying to open and I type it in full, it opens.

Previously, if, say, I wanted GIMP and I pressed `Super` and typed "GI", I used to get search results for "GI...", but now I get a blank screen underneath the search box. If I do press `Super`, type "GIMP" and hit `Return`, it opens GIMP.
