VideoOutput memory leak

Uniquename

Hi,

The Android project I'm working on has been recently upgraded to QT6.4.3, also changing the build system to CMake. I'm experiencing a memory leak occurring after starting the camera, when the output is used by the VideoOutput QML element.
When using a simple setup with CaptureSession, I'm getting the following warnings after calling camera.start():

I Gralloc4: mapper 4.x is not supported
W Gralloc3: mapper 3.x is not supported
[SurfaceTexture-33-26350-1] bindTextureImage: clearing GL error: 0x500
[SurfaceTexture-33-26350-1] bindTextureImage: clearing GL error: 0x500

The following errors appear when unloading the QML page:

E BufferQueueProducer: [SurfaceTexture-51-26350-2](id:66ee00000002,api:4,p:9863,c:26350) cancelBuffer: BufferQueue has been abandoned

The QML code I'm using to reproduce this:

import QtQuick
import QtMultimedia
import QtQuick.Controls 2.5
Item {
    width: 640
    height: 360

    CaptureSession {
        imageCapture: ImageCapture{
            id: cap
        }

        camera: Camera {
            id: camera

            focusMode: Camera.FocusModeAutoNear
            customFocusPoint: Qt.point(0.2, 0.2) // Focus relative to top-left corner
        }
        videoOutput: videoOutput
    }

    VideoOutput {
        id: videoOutput
        anchors.fill: parent
    }

    Button{
        onClicked:{
            if(cap.readyForCapture){
                cap.capture()
            }
        }
    }

    Image{
        id: imgPreview
        source: cap.preview
    }

    Component.onCompleted: {
        camera.start()
    }
}
