• the thread had no solution when I wrote, I assumed it was flatpak

• You seem to have found a reason now, and it indeed seems to be flatpak again

And the reason is always the same, flatpak runs as intended and breaks stuff by default, people find issues, write a thread here to ask for proper flags and settings for stuff that works natively out of the box 90% of the time when installed from the native repos in serious distros.

Which brings us back to my point: it solves the wrong problem for the wrong people. Provides sandboxing and isolation for people that use it as a covenient software source unaware of its quirks.

For those aware of them it is useless because they will know enough to do the isolation and sanboxing were it matters themselves.

To be fair you did some good work understanding what was happening, so I ask you: why do you use flatpak?
