Tried also env -u __GLX_VENDOR_LIBRARY_NAME vglrun google-chrome and it didn't help.
Log reported something went wrong in function CreateDummyWindow(Display* display): https://github.com/chromium/chromium/blob/master/ui/gl/gl_surface_glx.cc It looks that such dummy window inherits visual from parent (the root window), then the list of available GLXFBConfig is searched for one matching GLX_VISUAL_ID. No match is found and Chrome falls back to software rendering. Provided that Visuals and GLXFBconfigs come from different X server, is it possible they match somehow?
