I was trying to render some image in a Linux Docker with EEVEE render Engine. As I learnt EEVEE needs a display(Blender 2.8: "Unable to open a display" by the rendering on the background (Eevee)), i use Xvfb to create a virtual screen.
The command I used for create a virtual screen in Docker container is
Xvfb :0 -screen 0 3840x2160x16 -ac +extension GLX +render -noreset &
blender -b Panda.blend -P myscript.py -o out -f 1
After that I get a result with wrong texture and color. For the same file and script ran on my MacOs,I can get the correct on shown in the left img. I think the strange result might related to frame buffer/Rendering buffer, but I have no idea how to fix that.
