drm/amd/display: Fix underflow when playing 8K video in full screen mode
[ Upstream commit 4007f07a47de4a277f4760cac3aed1b31d973eea ]
[Why&How]
Flickering observed while playing 8k HEVC-10 bit video in full screen
mode with black border. We didn't support this case for subvp.
Make change to the existing check to disable subvp for this corner case.
