Any support for contourgl?

[kennyhuynh125]

I have a feature on my app that could display up to 10+ different contour plots. Once it hits about 10+, the performance is affected. I know that there is a contourgl plot option, but after looking through some of the other issues, it seems that it is not very supported and has many bugs.

I have tried to use it as well and ran into some issues (think it was something to do with the shader). I'm wondering if there has been any improvements to contourgl or if there is another solution to getting faster performance while using contour (maybe via canvas instead of svg)?

I'm afraid that's right - contourgl is known to be buggy and we haven't seen enough interest in it to justify improving it. If you're interested in helping out we'd happily accept a PR, or we would accept sponsorship to accelerate it.
