need EGL_KHR_surfaceless_context extension

I get the following error for blur_effect img.png -o blur_img.png:

image has no alpha
try to open /dev/dri/renderD128
backend name: drm
need EGL_KHR_surfaceless_context extension

I use Arch Linux and installed the program from Community repository as blur-effect package.

I don't know where is this blur_effect command comes from, I think it's blur_image? use blur_image -d /dev/dri/renderD128 img.png -o blur_img.png if under X11, or just sudo blur_image img.png -o blur_img.png. if neither works, plz paste output of glxinfo here.
