Question about driver compatibility with the GUID_WICPixelFormat32bppPBGRA and MFVideoFormat_ARGB32 formats.

Is anyone aware of any issues with the GUID_WICPixelFormat32bppPBGRA and MFVideoFormat_ARGB32 formats?

This problem affects TouchXPRT (touchxprt.com). One of its scenarios combines photos to create a slide show. On some systems creating the slide show took a very long time and the video was not rendered correctly. So far, we have only seen this problem with some of the more recent AMD drivers. (e.g. version 15.100.1020.1005) We were able to work around this issue by changing the pixel format from from GUID_WICPixelFormat32bppPBGRA to GUID_WICPixelFormat32bppBGR and changing the media format from MFVideoFormat_ARGB32 to MFVideoFormat_RGB32. However, we would like to be as sure as we can that these changes have resolved this issue.
