I've got a strange problem;)
Many times a day, some materials inside the 3D View goes black. The only thing I need to do is switch first to Simple Shading (Vectorial) and then back to OpenGL Shading and then it's fine again.
It's completely black when I'm far from the object and it gets less and less black the closer I get. When I'm totally up close to the object, it has its original texture/color.
It's a nuisance;)
It's probably because I run ArchiCAD inside VmWare on Ubuntu GNU/Linux 17.04. It has really always been like this from ArchiCAD 19 and 20 and different upgrades of VmWare and GNU/Linux.
It's probably because there is some issues with the OpenGL inside VmWARE or some combination with my graphics driver and VmWare. It can be many things, but anyone else had this? Any pointers as to how I can troubleshoot it?;)
