Description webkit-bugzilla 2022-09-27 09:08:55 PDT

The WebGLRenderingContext variable is not defined on the window. This appears to be a regression. Only WebGL2RenderingContext is defined. I've tried enabling/disabling WebGL 2.0, WebGL Draft Extensions, and WebGL via Metal to no avail.

window.WebGLRenderingContext is defined in both Safari Version 16.0 (17614.1.25.9.10, 17614) and Safari Technology Preview Release 153 (Safari 16.0, WebKit 17615.1.4.1).

What's your specific browser and OS version? Are you on an Intel Mac as is reported here? What machine model (About this Mac, "System Report", "Model Identifier")? E.g.

  Model Name:	MacBook Pro
  Model Identifier:	MacBookPro18,2
  Chip:	Apple M1 Max

Sorry for the delayed response. The issue still seems to persist on Safari 16 and macOS 13.

This is Safari version 16.3 (18614.4.6.1.6) on macOS 13.2.1 (22D68) on an intel mac:

  Model Name:	MacBook Pro
  Model Identifier:	MacBookPro16,1
  Processor Name:	8-Core Intel Core i9
  Processor Speed:	2.4 GHz

Thanks for the report.

Last entry of "Experimental Features" and "Internal Features" menu items is "Reset All to Defaults". Could you still retry by clicking both of those and restarting the browser?
