Automated Screenshot Tool Failure - Error 400 (Image dimensions exceed 2000px) #300407
Description
Type: Bug
I am encountering a persistent loop error when using the built-in "Take a screenshot" feature in Copilot. The automated capture process generates an image that exceeds the system's own technical limits, causing the request to fail before it can even be processed.
Error Message received:
Reason: Request Failed: 400 {"message":"messages.5.content.213.image.source.base64.data: At least one of the image dimensions exceed max allowed size for many-image requests: 2000 pixels"}
Steps to reproduce:
Use the "Take a screenshot" command or button within Copilot on a high-resolution display (e.g., 4K or Ultrawide).
Copilot triggers the automated capture.
The system returns an Error 400 because the captured image is larger than 2000px.
The chat enters a loop where it is impossible to retry or fix the capture within the same session.
Expected behavior:
The automated screenshot tool should automatically downscale or compress the image to fit the 2000px limit before sending it to the model, or provide a cropping tool to stay within limits.
