Black preview 3D on AMD Radeon R7 370.

Black preview, both 2D and 3D, on Windows 10, both Mesa3D and Intel 620/Nvidia GTX 950M (laptop).

Am I missing some render, update etc. command?

I can confirm this. Only getting Black preview in both 2D and 3D view with AMD Radeon RX 480 8GB on "Radeon Software Version 19.9.2".

Same here with R9 280X, win10pro, thought it will fix with some updates but already on 0.4.0 and still unusable for me sadly

0.4.0 works for me,  with some updates of Windows and of Nvidia video drivers.

I have the same issue with my HP EliteBook 840 G3 with an Intel HD graphic 520 driver version 26.20.100.7263. I have the same problem using both v 0.40 or 0.32
