I tihnk you want VisPy:

https://vispy.readthedocs.io/en/latest/

It's a plotting package with a kinda like  matplotlib API, built on OpenGL.

Unfortunately, it doesn't look like it's been updated in a while -- from
teh docs. But the gitHub project is active:

https://github.com/vispy/vispy

So maybe it's only the docs that haven't been updated!

But probably  a much better option than trying to shoehorn GPU rendering
into MPL.

The problem is that while MPL was designed to be "backend" independent --
so it is "easy" to plug in an alternative renderer, the rendering model is
not really well suited to GPU rendering -- it would take a lot of
refactoring to really be able to take advantage of the graphics card.
