I updated from 2017.2 to 2019.2. For a while, everything went well.
At some point, a black screen appeared in the window with the editor, even tabs with the console and the game are not visible
I have found some solutions (doesn’t help)
- Install last version driver of videoadapter
- switch from DX11 to DX9 (dx9 not supported in unity 2019.2)
- high perfomance to unity in video utility
Please help
