Chrome Extension Screenshot Issue: Only Capturing Visible Area?

Tifany Clemenceau · 2025-04-14 08:36:18.131014+00

Hi, when I attach a screenshot with the chrome extension, it looks like it takes only what I can see on the window. But I think before (until last week), it took the whole page. Is it just me?

I see the same thing, though I don't recall what it was before. Looking at the code, it seems the intention is to do a full capture if the page is text/html, and only a "visible capture" otherwise. But it doesn't appear to work that way, as only the visible content is captured even for HTML. https://github.com/dust-tt/dust/blob/422d0ec2167c638aea4dcb048f5da634f97805e9/extension/platforms/chrome/background.ts#L274-L317

Thanks for flagging Tifany Clemenceau! I confirm that the expected behavior is to have it take a screenshot of the full page. I'll share the bug with the team 😊

Adding Thomas Draier (Dust) as I was just chatting with him about that. Though in my case, playing with it some more, I commonly run into a cases where the screenshot logic fails with Cannot get page content. Failed to get a screenshot of the page.

I've just tried and it seems to work as before for me - it scrolls and takes the whole page in one or multiple files. David Ebbo can you send me your html file so that i can test on it ?

It's quite trivial: https://gist.github.com/davidebbo/8a075cbfb14cb148984834cb38567d48. Works for me full screen, but fails when I reduce my window.

for .txt file it does not scroll at all, but if i use it with .html it works well - in all cases I don't see the error you got

can you right click in extension / inspect , try again, and show me what you have in the console when you get the error ?

This has some context: https://issues.chromium.org/issues/40764505. Seems there is a quota of screenshot per second. But then it' s puzzling that it doesn't affect everyone. BTW, I didn't mean to hijack Tifany Clemenceau’s issue, since she's seeing something different.

seems a matter of config (although I don't see how to easily change it) - weird that we don't have the same values. But yes orginal issues from Tifany Clemenceau looks different - capturing the whole page only works for html documents, and maybe not on all (depending on the structure of the document)

I'll open a GitHub issue for my issue. And it is not by at all urgent if I appear to be the only one seeing it...

Ok, let's use https://github.com/dust-tt/dust/issues/11991 for my issue, and focus on Tifany's issue here. Tifany Clemenceau could you link to a specific page where you see this? Thanks.
