WebGL is not supported by your browser - Plotly


Since this morning I am not able to generate 3D charts with plotly package. On the Viewer window I get the message: WebGL is not supported by your browser - visit https://get.webgl.org for more info

Clicking on the link, it opens a page in my browser (Safari) where it shows that webgl is working properly. If I run the script directly in R, the chart is shown in Safari.

I am working in a macOS Sierra, R 3.5.1, RStudio 1.2.964.

Any help would be appreciated.


One of the staff might be able to chime in here, but I suspect this is a case of the internal RStudio viewer actually not supporting WebGL. It may not be using Safari, so I'm not surprised that there's a difference there. Hopefully we can confirm that for you, though, @RgrNormand :slight_smile:

I agree with your assessment @rensa. Nevertheless, it used to work quite well in prior versions.

Ah! Well, that's another matter. Do you mean previous versions of RStudio, or previous versions of Plotly?

Prior versions of RStudio. It works correctly when I use pure R.

And other charts from Plotly also work well.

What kind of hardware are you running on? (By any chance, a new-ish Mac Pro?)

It'd be helpful to know what graphics display is reported in the About this Mac system dialog.

@kevinushey: Old computer, MacBook Air 2012 with Intel HD Graphics 3000.

Anything else?

Can you also share the output on the Help -> Diagnostics -> Show GPU Diagnostics page?

You might also try toggling some of the graphics-related options on the Advanced options page:

No changes when trying different advanced options.

@kevinushey I have provided the info you asked for, but your system considered it a spam. It should be freed soon.

Nevertheless, if I try the last stable version of RStudio, it works correctly.

With the new version...

@kevinushey: Any news about this issue?

There's a speculative fix for this in the newest daily builds of RStudio -- can you give it a download and let me know if WebGL is working again?

Unfortunately no.

What if you explicitly switch to using software rendering?

Same result. I have tried this in the past. With the last stable version, it works with auto-detect.

Which version do you mean by 'last stable version'? Do you mean the previous preview release? Can you confirm which version of RStudio that was just so we're on the same page?

(My confusion here is just because the stable release of RStudio, v1.1.456, does not have an option for changing the rendering engine)

My mistake. RStudio v1.1.456 works correctly and there is no option.

Can you also try forcing OpenGL as the rendering engine, and checking the Ignore GPU blacklist + Disable GPU driver bug workarounds checkboxes?

Sorry for my delay @kevinushey. I was not aware of your message.

It didn't work, unfortunately.
