Flatpak apps can still have access to the host ressources, like the file system. The nice thing is that you can see those permissions beforehand and adjust them if necessary. Flatseal simply has the permission to make those adjustments for other flatpak apps. Take a look at Flatseals manifest file, that should make it obvious.

Protontricks

Look at https://github.com/flathub/com.github.git_cola.git-cola/ which has git as a runtime dependency.

Hi all, I've installed the flatpak version of ungoogled chromium on my ubuntu 20.04 machine and it has been working like a charm. However, I need to apply a policy .json file. In deb chromium I would put it in /etc/opt/chromium/policies/managed/. On flatpak version I am not clear on what folder to choose. I obviously tried using /etc/opt/chromium/, /etc/opt/chrome, /etc/chromium, ~/.var/app/com.github.Eloston.UngoogledChromium/, ~/.var/app/com.github.Eloston.UngoogledChromium/config/chromium/ but all without any results - the chrome://policy page in chromium is empty and doesn't show any policy to be set. I found that the flatpak "extensions" are used, but I didn't find any documentation on how to use this. I also tried giving the app access to the whole disk using flatseal but no avail.

Flathub (Linux)

I am not familiar with the process at Flathub. But as far as I understand, the developer of CopyQ has already made an appropriate update (https://github.com/flathub/com.github.hluk.copyq/pull/53). Maybe these updates will be shown at flathub.org only with a time delay.

Now, what I was trying before just setting the version was to use protontricks, you can install it in the software repository in desktop mode. Then follow the flatpack install instructions

There's a script for that here: https://github.com/flathub/com.github.Eloston.UngoogledChromium

GNOME runtime bump to 43 for Haguichi is now merged. Might take a few hours to get published.

See release notes for details.

As long as you don't have a profile applied it should not override anything. Otherwise it will set several settings and override the shaders you have specified in your mpv configuration. The default profiles are defined here, which you can edit if desired.

If you use the MPV Shim client, I have included some video upscale shaders, which you can turn on. You can turn it on by pressing c and using the menu to select a video playback profile. Sometimes there are problems related to graphics card support, which breaks video playback entirely if you're unlucky. You can disable them with k if video playback breaks.
