Claude Code v2.1.242

Window screenshots no longer trigger spurious "take a new screenshot" warnings

You'll notice

Window screenshots no longer produce bogus "take a new screenshot" warnings before clicks.

What

Before clicking, Claude normally re-captures a crop and compares it against the last screenshot, warning if the screen changed. Captures that carry the window frame size now skip that check outright, so the warning is never produced for them.

Details
  • Screenshots from the macOS app-scoped tools can now report the window's frame size separately from the captured image size, and percentage-to-pixel coordinate maths prefers the frame size when present.
  • No flag controls this; the check is skipped whenever the reference screenshot has a frame size.
  • The frame-size field does not exist in the previous build.
Evidence

Screen content at the target location changed since the last screenshot. Take a new screenshot before clicking.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
