## What this fixes
Full-page screenshots via the Firecrawl `/scrape` endpoint fail randomly: with `formats: [{type: "screenshot", fullPage: true}]`, some pages capture only the hero section at the top, or render a full-height image with the bottom half blank. `waitFor`, scroll actions, and End/Home key presses do not fix it, and the affected pages cut off at the exact same vertical position each time.
## The fix
This was a Firecrawl-side rendering bug in how the headless browser captured full-page screenshots, not something scroll/wait params could work around. The team rebuilt their internal screenshot handling and the reporter confirmed after testing: full-page screenshots on previously broken pages were now working. If you hit truncated full-page screenshots, retry against the latest build.

## Why it happens
The thread above nails the cause, so the fix addresses that directly rather than symptoms. Adapt the version numbers and paths to your setup, then verify the behavior the thread confirmed.
