That's kinda strange... on my version of 0.18 the opengl32sw.dll file is nowhere to be found?

Thank you so much @Build-0-Matic !!!
I copied "opengl32.dll" into the mentioned "bin" folder and the FreeCAD 0.18 black screen problem was instantly fixed / On Windows 10. What a joy you gave me!

And why doesn't Microsoft fix this issue, was the issue already reported to them?

P.S. As Windows 10 is still officially supported.

It worked for me also on Windows 10 - I just downloaded the 64 bit version, extracted it “here” (the download folder) then copied and pasted it into the bin folder. Thanks Build-O-Matic - what a great forum this is. :D

The issue seems to be mainly with embedded graphics accelerators.

For FreeCAD, just copy the modified opengl32.dll into the Program Files\FreeCAD 0.18\bin folder.
Here is the link to the DLL file.

The file is compiled by Federico Dossena and not me.

This issue also occurs in other software, e.g. KiCAD as well (needed a workaround there also)
