Summary of the bug:
When capturing a windows explorer window with gdigrab, the effect is like
a black layer layer with some transparency in front of the content and the
result is not the same as the source.
This problem doesn't occur when capturing Desktop (instead of title=XXX).
How to reproduce:
{{{
% Open a windows explorer window (win+r Documents enter)
% ffmpeg.exe -f gdigrab -i "title=Documents"
ffmpeg version 4.2.3 (also occur in 4.0 version)
built with gcc 9.3.1 (GCC) 20200523
}}}
