A severe bug in ATI display driver in Windows Vista and Windows 7 for deinterlacing 1080i video using Vector Adaptive (VA) mode.
We met a severe bug in ATI display driver in Windows Vista (both 32-bit and 64-bit) and Windows 7 (both 32-bit and 64-bit) for deinterlacing 1080i video (both MPEG2 and H.264) using Vector Adaptive (VA) mode.
If we enabled Aero glass effect (default enabled) in Windows Vista or Windows 7, when watching 1080i MPEG2 or H.264 video using DxVA video acceleration, the display driver will fall back to Bob deinterlacing mode and can't choose other modes besides Weave. While watching SD video using DxVA, the Vector Adaptive mode is automatically selected.
This is unacceptable because Vector Adaptive mode is the best deinterlacing mode, it's annoying and unreasonable that every time we need to disable Aero effect in Windows Vista or Windows 7 to allow choosing this mode when watching HD content.
This is easily reproducable in the latest Catalyst 9.3 driver. I'm using ATI 4550 and ATI 4850, and from my friends, their 4870 cards all have this major problem.
Please fix this severe issue in the near futhure, hopefully in Catalyst 9.4.
