I realized that not only offscreencanvas doesn't work on my machine, webgl doesn't work at all. I checked about:support, firefox can detect my nvidia 1080ti gpu, and I have webgl working fine under chrome. I searched, someone said this might be a bug in nvidia driver, if firefox is launched with sudo, the issue will be gone. I tried, but I wasn't able to start firefox with sudo, I saw errors with Mir. another error message I saw with the terminal was libGL.so can't find the right fbconfig or something. I'm using ubuntu 17 with firefox 64/61.
