Hi m0rv, My guess is the "regression" is caused by commit:
https://www.winehq.org/pipermail/wine-cvs/2020-January/141298.html

So winetricks is really at fault here i think; it should set the key
HKEY_CURRENT_USER\\Software\\Wine\\Direct3D\renderer
instead of 
HKEY_CURRENT_USER\\Software\\Wine\\Direct3D\DirectDrawRenderer

Could you try if renaming the key from "DirectDrawRenderer" to "renderer"
brings back the previous behaviour?


That being said, two further notes:

1. I`ve never seen these glitches while testing Logos. Does this happen for all
users or only for a few ones? As I already said in previous comment, I`m
guessing it`s related to graphics card/driver issue

2. I`ve noticed that setting the aforementioned key (or disabling hardware
acceleration via key
https://docs.microsoft.com/en-us/dotnet/framework/wpf/graphics-multimedia/graphics-rendering-registry-settings)
makes the videos _NOT_ play (!). They only play for me with "normal" settings
(so no regkey set). But maybe some other settings might work around this again,
don`t know, enough issues to keep us busy testing ;)

Regards
