Summary WebGLRenderingContext undefined
webkit-bugzilla
Reported 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

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?
