Coordination inaccuracy issue

Gemini 2.5 Computer Use Preview exhibits inconsistent behavior regarding the accuracy of `click_at` coordinates after a certain number of iterations. While the `output_text` shows a `reasoning` with valid coordinates within the normalized `0-1000` range, the `function_call` `click_at` action often provides coordinates exceeding this maximum, leading to incorrect clicks. This issue seems to manifest after approximately `15` iterations. I am attaching a llm logs of the output_text and function_call from a recent instance where this occurred.

Please provide any additional information required for your investigation.

Start with the attached JSON LLM log, comparing the output_text reasoning coordinates with the computer_call click_at coordinates after about 15 iterations. Reproduce the behavior with Gemini 2.5 Computer Use Preview and determine whether the out-of-range coordinates can be consistently observed. Done means producing a reproducible finding and a documented explanation or actionable report.
