Screen after few seconds of rendering

Hello
using the following Direct3D options, I've finally managed to run Zorks:
DirectDrawRenderer=opengl 
RenderTargetLockMode=readdraw

However, the screen render still is not 100%, it looks like there is some sort
of incremental filter for static parts of picture.

See the attached pictures for more info, see the link below for demo installer
and Installation HOWTO.
