SUMMARY
When I update or install Flatpaks from Discover, Plasma will freeze for a couple of seconds near the end of the update or install task. I've tested this on my laptop and desktop, and it happens on both. People in the Fedora Kinoite Matrix room have also reported the same problem.

STEPS TO REPRODUCE
1. Open Discover
2. Try to perform an update, or install a Flatpak

OBSERVED RESULT
Plasma freezes for a few seconds near the end of the update or install task. 

EXPECTED RESULT
Plasma doesn't freeze for a few seconds.

I have the same issue from time to time. It looks like it does Flatpak updates heavily in parallel and that creates a lot of IO and thus the freeze.

@Timothée, can you maybe test this and see if it makes your life any better?
