[PATCH 2/2] winex11.drv: X11DRV_ChangeDisplaySettingsEx: enhance failed mode message The failed mode error message simples dumps all the mode fields that were being tested. Change this output so that only the mode fields explicitly being matched against are displayed. Make the failed message use formatting consist (with an earlier trace message in this function).
