I installed the latest Rhino 9 WIP, but I quickly noticed that it destroys some of my custom display modes. Many of them look quite different than how they appear in Rhino 7. Even the most basic display mode that I use, Bobi 1, which is supposed to use scene lightning and rendering material, is completely different and impossible bright in Rhino 9 WIP, whereas it has a strong shading in Rhino 7. All settings are identical between the programs, the display modes are a direct import from ini files originally exported from Rhino 7.
There are no lights in the default startup scene in either program, “Sun” is off, “Ground plane” is off, too.
Here is the interesting part. My display mode in Rhino 7 uses “Scene lighting”, whereas the same setting in Rhino 9 WIP causes the bug showed in the pictures above. However, if I go to the settings of my display model in Rhino 9 WIP and change the lighting to “Default lighting”, the shading looks almost identical with the one in Rhino 7 which uses “Scene lighting”. Both, “Scene lighting” and “Default lighting” in Rhino 7 seem identical, but they differ a lot in Rhino 9 WIP.
Also, the vertical slider in Rhino 9 WIP’s options is way too thin, thus the navigation is way less convenient compared to Rhino 7 that features a nice thick slider.
Other display modes are less affected (in a negative way), but they still exhibit some differences in the shading, highlights and transparency.

EDIT: I figured out that changing “GPU Technology” in Rhino 9 WIP from “DirectX” to “OpenGL” fixes most of the issues with the custom display modes. However, there are still very minor differences, but the problem is that display modes like “Bobi 1” and others that rely on “Scene lighting” look completely different in Rhino 9 WIP when I switch to “DirectX”. They literally glow and no longer can take advantage of the strong shading that the “OpenGL” setting provides.
Is there a way to reset all settings from Rhino 9 WIP and re-install a fresh new copy without any residue settings and customization that I imported from Rhino 7? I wan to try to set there manually directly in Rhino 9 WIP, because many of the imported settings are not working properly anyway.
I already modified and repaired Rhino 9 WIP, but it still uses my imported settings from Rhino 7, so it looks like it reads them from some system folder.
Also, Rhino 9 WIP crashes every time when I open the pop-up menu and hover over the icons with the mouse pointers. A few seconds later the pgoram crashes. Every single time.
