If you still don't get any results, check if hardware-acceleration is enabled in Chromium settings, Google tends to disable this setting by default since version 43. In this case that was the problem for me after I updated GPU drivers, overrode the GPU blacklist, and so and so.
Maybe too old your video driver or not installed properly.
I had same problem too, but this solution fixed my problem without overrides!
