Threaded openGL

[12crowns]

OS: linux
NV driver: 390.25

X-Plane 11 will not run using primus. It needs threaded openGL
Error:
WARNING: could not set vsync - this machine's video drivers do not support the extension glXSwapIntervalSGI.
X-System Error:
X-Plane cannot run on your machine because it is missing needed GLX extensions.
You must have GLX_SGIX_fbconfig and GLX_SGIX_pbuffer available to run X-Plane 11.
Sorry.

GLX_SGIX_fbconfig and GLX_SGIX_pbuffer
are available according to glxinfo

X-Plane 11 runs fine using xrandr graphics offloading

Same problem here.

I get the same problem using nvidia-drivers-418.56. When I run through opriun -v I also get the following warning:

WARNING: could not set vsync - this machine's video drivers do not support the extension glXSwapIntervalSGI.

It also seems my card/nvidia-driver supports both GLX_SGIX_fbconfig and GLX_SGIX_pbuffer:

optirun glxinfo          
name of display: :1
display: :1  screen: 0
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
server glx version string: 1.4
server glx extensions:
    ...
    GLX_NV_swap_group, GLX_NV_video_capture, GLX_SGIX_fbconfig, 
    GLX_SGIX_pbuffer, GLX_SGI_swap_control, GLX_SGI_video_sync

Same problem here with debian, could anyone solve the issue yet?
