Running > <html><meta charset="utf-8"><body><canvas id="canvas"><script> > document.getElementById("canvas").getContext('webgl').getParameter(42624); > </script></body></html> prints out the following to console, as expected: > Error: WebGL warning: getParameter: parameter: invalid enum value <enum 0xa680> However, when running with OffscreenCanvas (gfx.offscreencanvas.enabled;true), the following > <html><meta charset="utf-8"><body><canvas id="canvas"><script> > document.getElementById("canvas").transferControlToOffscreen().getContext('webgl').getParameter(42624); > </script></body></html> does not print out any error diagnostics to console. Tested on Windows 10 x64 Firefox Nightly.

Not sure exactly where this problem would be, but it seems like Jeff would be a good person to know.

We aren't maintaining offscreen canvas at the moment.

I can't reproduce this issue. I see the error message in both cases.
