Since Firefox 75 and nightly currently 77 0a1 our WebAssembly 3D viewer has stopped rendering 3D graphics when assigning the canvas width height to the value it already has.

It appears the following commit has caused the regression.
https://phabricator.services.mozilla.com/D66827

If we resize the canvas or rotate in the 3D it temporarily comes back but as we update the canvas size per frame it loses the display again.

The workaround suggested to stop D66827 updating the size if it's identical and it does resolve it.
Our software runs onprem and not centrally hosted our customers are now all failing to render any graphics from FF 75.

Oh this has languished! Very sorry!

Is this still a problem for you, and do you have a link to a testcase?
