I am trying to get Blender cloud rendering with Nvidia GPUs to work. I am using Blender 4.1 as a module. When rendering using Workbench (or Eevee) I get an error, the render takes much much longer than it should (50 sec vs 2 sec), and after the render is done I get a segmentation fault. Here is the error before the render: libEGL warning: egl: failed to create dri2 screen libEGL warning: egl: failed to create dri2 screen libEGL warning: failed to open /dev/dri/card1: Permission denied EGL Error (0x3009): EGL_BAD_MATCH: Arguments are inconsistent (for example, a valid context requires buffers not supplied by a valid surface). The Nvidia drivers should be setup correctly, running nvidia-smi outputs this: +-----------------------------------------------------------------------------------------+ | NVIDIA-SMI 570.124.06 Driver Version: 570.124.06 CUDA Version: 12.8 | |-----------------------------------------+------------------------+----------------------+ | GPU Name Persistence-M | Bus-Id Disp.A | Volatile Uncorr.
