QRasterPlatformPixmap::systemOpaqueFormat returned QPlatformScreen::format without checking that the format was actually opaque. This caused several QPixmap tests to fail on Wayland because Wayland compositors don't communicate the native format of the screen, just a list of supported pixel formats, so we just return ARGB32_premultiplied in QWaylandScreen::format(). Rename the method systemOpaqueFormat to systemNativeFormat since that's how it's used most of the time. And do a conversion when we actually care whether the format is opaque or not.
