Reproduce the report on Windows with scrcpy.exe using the shown command, Android 13, and the listed device, then observe the display and renderer output over time. Compare the two attached screenshots and the scrcpy-server log to determine whether the blurry rendering is consistently reproducible; done means the cause and a reliable verification path are established.
