When I maximise to fullscreen in WM11, the widescreen borders top and bottom are a grey colour rather than black. I havent changed any default settings in WM, and the blacks in the fullscreen interface are perfect. The media files are encoded in widescreen so the borders are not part of the files themselves. I have tried some other media players, and they produce the black borders perfectly. How can I change these borders to black in WM? Thanks
