 I am not sure that it is right. I fear that the issue is in the XCB module
that declares RGBA but returns data that does not follow the order that
VLC RGBA wants (RGBA is only supported with a fixed order in VLC).

A solution/workaround may be to return RGB32 in the XCB plugin.

I will let courmisch comments.
