Tesseract: An Advanced Lemmy Client

The goal of Tesseract is to address as many things in Lemmy that annoy me as I can. I also trawl various "is there any way to [blank] in Lemmy?" posts to get feature ideas. Both of those lists are pretty extensive, so Tesseract has accumulated quite a few features.

Github: https://github.com/asimons04/Tesseract/

Hosted / Demo Instance: https://tesseract.dubvee.org/

Note that the hosted instance defaults to Lemmy World, but it is unlocked to be able to connect to any Lemmy server.

Announcements, support, and guidance for the Tesseract UI.

All instance rules apply here. Beyond that, just be civil and constructive.

[Bug][v1.4.29] Feed sometimes skips a whole load of entries (feddit.org)

submitted 1 week ago by Lucki@feddit.org to c/tesseract@dubvee.org

When scrolling through the feed it randomly happens to skip a bunch of entries. It suddenly jumps far down the feed for no apparent reason.

Some observations and possible cause thoughts:

I believe it skips one load batch (20) of entries.
Scrolling up those entries gets me back to where I was in the feed.
I think it happens when the last entry of a previous load batch expands an attached media item.
It's more apparent in media heavy feeds.
It's independent of the scroll speed.

Are you running it in podman on the same machine as you're running the browser?

Yes. They're both on the same desktop.

Firefox is the latest 134.0.2.

I do have that local media caching activated so it might be that the browser was still requesting or fetching media in the background even though I wasn't even in the feed anymore. I'll keep an eye on this and see if it is an issue in normal use when I'm not trying to replicate a scroll issue.

Well, I don't think it was Svelte(kit) or its dependencies. I rolled those back to the versions I had prior to 1.4.21, rebuilt, and performance on FF ESR 128 was still abysmal. The main feed worked okay, but once I opened a modal or got to a GIF animation, it was basically at like 5 FPS with one CPU fully maxed out.

So I downloaded the latest 134, un-tarred it to /opt, and loaded Tesseract 1.4.30 (since reverted to the current dependency versions), and performance is fantastic (comparable to Chromium on the same machine and non-ESR Firefox on my main laptop).

One thing I noticed about the ESR version on my dev machine was that it didn't act like hardware acceleration was working (for any website/app) where it does seem to work in the latest version. Could that possibly be an issue for you?
