/**
* A quirk where the orientation of the preview is incorrect while a surface to be used to
* configure on 2 different {@link CameraCaptureSession}.
*
* <p>QuirkSummary
* Bug Id: 128577112
* Description: Reusing a surface to create a different {@link CameraCaptureSession}
* causes incorrect preview orientation for LEGACY devices. Some GL related setting
* is left over when the legacy shim is recreated. It causes the 2nd
* PreviewCaptureSession to be rotated and stretched compared to the 1st one.
* Device(s): Devices in LEGACY camera hardware level.
