I when I try to open Okular which I've installed using flatpak, I see these two icons in my launcher:

After a while the Okular icon disappears and only the question mark one remains. What could be causing this and what could be a fix?

I'm on Ubuntu 16.04.

    You need to add a correct StartupWMClass entry to the application's .desktop launcher. Possible duplicate of Eclipse has two icons on unity launcher when I only want one – pomsky Mar 21 '19 at 10:38
  • Seems like this is the case. Though the solution there doesn't work directly since the .dekstop files aren't available in the usual locations for flatpak apps. I'll try to search where it is and if it can be overridden without flatpack overwriting it when it updates the app – Peeyush Kushwaha Mar 21 '19 at 14:12
