Bug spotted? (first post, sorry)

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

Made a really simple promp to get a design in html with fable 5 high no reasoning. It got stuck in some point and said “Takes longer then expected” then output this:
& “C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe” --headless --disable-gpu --window-size=1440,4400 --screenshot=“c:\Users\illia\Desktop\serwis komputerowy test\shot.png” --virtual-time-budget=9000 “file:///c:/Users/illia/Desktop/serwis%20komputerowy%20test/index.html”
[24676:18004:0713/131554.375:ERROR:chrome\browser\task_manager\providers\fallback_task_provider.cc:126] Every renderer should have at least one task provided by a primary task provider. If a “Renderer” fallback task is shown, it is a bug. If you have repro steps, please file a new bug and tag it as a dependency of Chromium .
790743 bytes written to file c:\Users\illia\Desktop\serwis komputerowy test\shot.png

After this it used like 9% of api usage and there are no traces in dashboard/usage for this request. Its abnormal because yesterday i did same prompt but generated design in png and it took 2% of api usage. I think usage should be similar (atleast not as dramatically different) because image tokens cost more then text ones. Can i get my api % back? haha

Steps to Reproduce

Turn on fable 5 high no thinking and paste this prompt with image attatched:

  1. Cel: przedstawienie serwisow oraz oferty, kontakt

strona ma smooth scroll

Glowna strona zawiera uslugi (ważne: podkreślić że ekspertyza jest darmowa), o nas, kontakt, testemonia (setki zadowolonych klientow, opinii - integracja z google?).

header to Floating pill navbar + glassmorphism (blur). zawiera logo firmy (png) oraz CTA button z hover animation. “Do kupienia”. Kiedy jest scroll w dol navbar sie howa i pojawia sie floating pill, kiedy sie scrollike w gore pill navbar wpasowuje sie i rozciaga zeby dopasowac sie w header na srodku

hero. sekcja to tekst Andrzej Zachara \n Serwis komuterowy \n A-KOMP (jest animowane Typewriter effect litera po literze), w backgroundzie jest pokaz slajdow. Trzeba wymyslec gdzie umiescic Zmieniajacy sie tekst wyswietlajacy oferowane uslugi przy zmianie obrazku

Dodać FAQ

  1. Paleta kolorów, Styl

Paleta: Granatowy + fioletowy akcent

Styl: long-scroll, minimalistyczny

Inspiruj sie elektronika (może być architektura PCB laptopa jako glowna idea), programowaniem przy designie komponentow i layoutu. Treść jednak zostaje niezmienna, główny cel to przedstawienie oferty ludziom nie znajacym sie bardzo na technologiach a wygląd ma nadac vibe.

W załączniku masz podany jpg w ktorym przedstawiono jak wyglada teraz strona. Napewno wez z niej dane, layout do zmiany wedlug uznania. nav ma byc taki jak w opisie. Bez obrazkow narazie. Wygeneruj design strony w html pliku (css i js tutaj tez)

Constraints: Write code in single line (formatter in cursor will do the job), use selectors only when neccessary and keep them short (one or a few letter only), same for var naming in js

Expected Behavior

normal api usage and no “taking longer than expected”

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report. Let’s break it down, there are a few different things here, and none of them is a bug where usage gets lost.

About the usage that “isn’t” in the dashboard. Your run is recorded correctly on the backend, no usage was lost. The fact that the Usage page shows 0% or doesn’t update is a known display bug on the Usage page itself. The data exists on the backend, the frontend just doesn’t show it. Thread here: High Load, and usage percentage shows 0% and does not update

Small note: on July 8 there was a broader incident. Along with the display bug, there were also issues with limit enforcement, but it was fixed the same day. Your run was on July 13, so it’s outside that window, so it most likely doesn’t apply here. Also, on a free-tier account you’re not billed in dollars. If you hit your included limit, you’d just get blocked, not charged. If you still have concerns about spend for a specific period, email [email protected] and they can check your exact account. We don’t handle account-specific spend checks on the forum.

Why the HTML used ~9%, but a PNG yesterday was only 2%. That’s expected. Generating a full single-file website is a multi-step agent loop with a lot of output tokens. You ended up with ~37k output tokens, plus the model rendered and screenshotted the result to self-check. One PNG image is just one call. Fable 5 High is a premium model, and on the free-tier included pool it gets used up quickly. For large generations I’d suggest Auto or a simpler model, it’ll be noticeably cheaper.

About msedge --headless --screenshot and the Chromium ERROR. That’s normal behavior. The agent rendered its HTML and took a screenshot to verify the result. The fallback_task_provider.cc line is harmless stderr from Edge, not a Cursor defect.

“Taking longer than expected” is a standard message on long turns, not an error.

Request ID for next time, it’s helpful for AI bugs: top-right chat menu > Copy Request ID (with Privacy Mode off).

Let me know if the Usage page still doesn’t start updating after some time.

Thanks for quick response. My bad didnt know writting html would be more challanging. Will see what can i do about it.
