Must have been some darn fine curry.

[-] [email protected] 22 points 1 month ago

I don't get that, what client are you using?

[-] [email protected] 16 points 1 month ago

Eternity. Only happens once in a while, like every couple of weeks.

[-] [email protected] 9 points 1 month ago

It's a known bug of Eternity. You have to live with it, or switch to Voyager.

[-] [email protected] 1 points 1 month ago

I think it happened on Infinity back in the Reddit days as well

[-] [email protected] 0 points 1 month ago

Never happened to me on Jerboa!

[-] [email protected] 9 points 1 month ago

Which makes sense for an Eternity bug

[-] [email protected] 1 points 1 month ago

But someone mentioned it also happening on Voyager? So it seems that it happens on both, and doesn't happen on Jerboa

100% guessing here, but native apps sometimes use recycling virtualized lists. That means as you scroll the list will reuse the container that renders the post title and image. Often the image is still being fetched but you already know the title. So as you scroll, it reuses a post you previously saw, instantly swaps in the new title, but the new image is still loading, so an image from a previously post in the list is displayed.

the result is you many only need to render and reuse 10 posts in the list, even if the list contains hundreds of posts.

Idk if that made any sense at all, but keep an eye out if the title is new but the image was previously seen.

Yeah, that's why key props are important. And sanity checks too. But too many programmers these days just turn off eslint rules without understanding why they exist

I’m not a recycling list expert, but I think the more keys you use the less react is able to reuse components in the list. So this is one area where keys are actually worse. You may be able to use them only on the image part of the post, but packages like expo-image have a recyclingKey prop you are supposed to use instead. But I found expo image to not work very well so 🤷

But I think think the app we were referring to isn’t react native? Idk how native recycling lists work tbh so maybe you’re right about the key thing.

No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.
