~/.var/app contains empty folders from apps that are not opened

I’ve been using Kinoite for some time and noticed that my ~/.var/app/ directory gets consistenly filled up with app folders I don’t have installed, like google chrome, chrome dev, ungoogled chromium, chromium and librewolf. All flatpaks. I don’t know why this happens and all the folders are empty. These are the flatpaks I have installed:

flatpak list --app

Even though Chrome is installed, I never used it as it’s for another user. If chrome is not installed, ~/.var/app/ gets populated with the same empty folders above.

Looks like a bug in Discover or something else. Does this also happen in Silverblue? I got 2 Kinoite systems where this happens consistenly.

On my system, these folders also show up, though I don’t have Chrome or Chromium installed. But they aren’t empty on my system:

~ ❯ tree .var/app/com.google.Chrome
.var/app/com.google.Chrome
├── config
│   └── google-chrome
│       └── NativeMessagingHosts
│           └── org.kde.plasma.browser_integration.json
└── plasma-browser-integration-host

4 directories, 2 files

~ ❯ tree .var/app/io.gitlab.librewolf-community
.var/app/io.gitlab.librewolf-community
└── plasma-browser-integration-host

1 directory, 1 file

It appears that this has to do with the Plasma integration for these browsers.

That’s right. Relevant thread from the KDE forum:
