letters are doubled when searching in launcher
When I type something in the search bar of the launcher I always get them doubled. When I want to delete one letter again, it also deletes two at a time.
I don't think it is a keyboard issue because the problem only occurs in the launcher.
Another issue that is most likely connected to it is that sometimes when I type fast in another window, suddenly some app starts launching. When I open the launcher after that the app that just launched is the first one that appeared after typing a single letter which I actually didn't do and must have happened in the background.
What exactly could be causing that issue? Anyone else experienced something similar?
I have the latest Mojave installed.
