This happens with any use of the hwmap filter in the derive_device configuration with input being HEVC decoded via dxva2 with dimensions that aren't 128-pixel-aligned and output being QSV; eg: ffmpeg.exe -codec:0 hevc -hwaccel:0 dxva2 -hwaccel_output_format:0 dxva2_vld test.mkv -filter_complex '[0:0]hwmap=derive_device=qsv[0];[0]scale_qsv=format=nv12[1]' -map[1] -codec:0 h264_qsv output.mkv
