Hi,
I am suffering from the phenomenon that the translucent part of a PNG image is drawn black.
This happens only in Safari on iPhone.Moreover, it occurs when using the video player plug-in.
This phenomenon does not occur on a pc or tablet.
The original png image.

The semi-transparent part becomes black as shown in the picture below.
The images of the women are mp4 movie and jpg poster.
