New cards "good" button always 2 days on linux

Hello, sorry, I saw a few similar topics but didn’t find any solution.
Basically, when viewing new cards for the very first time, the Good button always sets the card due date to 2 days. Happens only on linux desktop (Fedora)

This is inconsistent with my other devices, both windows and android where the good button for new cards shows a value between 2 and 5 days. All devices are synced

Any ideas why this might be happening?

Are you using a different version of Anki on Linux (especially a significantly older version) than on your other devices?

Nope, Anki is up to date on all devices. I tried downgrading and installing the flatpak version but nothing changed.

I created two sample decks of 10 cards each and this is the situation when always pressing the Good button:
deck 1 (windows)
2 days → 3 cards
3 days → 4 cards
4 days → 3 cards

deck 2 (fedora)
2 days → 7 cards
3 days → 2 cards
4 days → 1 card

Things get a little better as I keep doing reviews but still, over 50% of the cards reviewed are being set due on the same day.
IDK, it seems that FSRS is not working properly for some reason.

That doesn’t look like “always 2 days” – that looks like a random assortment of intervals within a certain range, which is what you’d expect from “smart” fuzz and load balancing.

Sorry, my bad for not specifying.
The “always 2 days” I was referring to in the first post applied to imported decks that I review on Windows. When I review the same decks on Linux, the new cards are indeed always set at 2 days.

Plus, that doesn’t seem all random to me. Yes, approximately 50% of the cards are distributed randomly, but the other 50% seem to be set to the “first” day of review for the Good button, which is: 2 days for the first review, 7 days for the second, and so on…

In the long term, that creates an unbalanced workload, with specific days that have hundreds of reviews and others only a couple of dozen. None of this happens on Windows.

I don’t know how the algorithm works, so maybe it is an expected behavior, but to me something seems wrong, that’s why I asked.

Unless you’re importing someone else’s review history/scheduling with your decks [which you should never do], there’s no difference between a New card that you made and a New card that you imported. But now that you’re talking about different decks – have you considered whether all of those decks are using the same Options preset? Different Options presets will have different settings and can result in different scheduling.

“Random” doesn’t mean “evenly distributed” – so there wouldn’t be anything unusual about an uneven distribution in a small sample of cards. But there are also other factors going into when cards are scheduled – like load balancing, which takes into account the cards that are already scheduled – and (for cards that aren’t New) the specific card’s review history and memory state.

You didn’t mention that. Is that what’s happening in your collection? Or is that just what you fear could happen? That would be an indication that load balancing isn’t working.
