--- Comment #7 from Jonathan Strander mblackwell1024@gmail.com --- Created attachment 58595 --> https://bugs.winehq.org/attachment.cgi?id=58595 The Witcher 3: Time lapse of screen distortions
Taking 7 rapid screenshots of the same scene and layering them shows how noisy/busy this actually is. They (odd black shapes) are constantly dancing all over the screen. I am sure if I had enough images to layer in it would easily cover everything.
Note that with HBAO+ enabled (or all SSAO disabled) everything is completely normal.
