is similar but not. I cloned getUserMedia with "clone()". On the device with ios16 it is easy to reproduce the bug.

When the permission request message appears, very quickly it is accepted and the bug appears.

on devices with version 15 I can't reproduce this error.

  const normalStream = await this.window.navigator.mediaDevices.getUserMedia({
        audio: false,
        video: {
          facingMode: 'environment',
          width: { exact: 150 },
          height: { ideal: 720, max: 960, min: 480 },
          // aspectRatio: { ideal: 1 },
          // eslint-disable-next-line @typescript-eslint/ban-ts-comment
          // @ts-ignore
          ...(this.window.navigator.mediaDevices.getSupportedConstraints().resizeMode && {
            // resizeMode: 'none'
            resizeMode: 'crop-and-scale"'
          }),
          frameRate: { ideal: 60 },
        }
      })

      const fakeStream = normalStream.clone()
      const mediumStream = normalStream.clone()

      await Promise.all([
        ...mediumStream.getTracks().map((x) =>
          x.applyConstraints(
            this.getVideoConstraints({
              aspectRatio: 1.333,
              width: { min: 960, ideal: 1280, max: 1440 }
            })
          )
        ),
        ...fakeStream
          .getTracks()
          .map((x) =>
            x.applyConstraints(
              this.getVideoConstraints({ width: { min: 960, ideal: 1280, max: 1440 }, frameRate: { ideal: 25 } })
            )
          )
      ])

      this.cameraNormalAperture.nativeElement.srcObject = normalStream
      this.cameraMediumAperture.nativeElement.srcObject = mediumStream
      this.fakeCamera.nativeElement.srcObject = fakeStream
