 There are important limitations when changing the viewport:

+- **Headful browsers**: You can't resize the viewport while [live view](/browsers/live-view) is active or while a [replay](/browsers/replays) recording is active unless you set the `force` flag to `true`.
 - **Headless browsers**: Changing the viewport triggers a Chromium restart, which takes several seconds and may disrupt active CDP connections.

+If you need to resize the viewport while replay playback is active, set `force` to `true` in the update request. Kernel stops the active recording or replay process, applies the new viewport, and then restarts it. This creates multiple replay segments for the same browser session.
