[Solved] WebGL2 enabled, but sites say it is disabled by the browser.

  • When I try to go on any site using WebGL2, it says that opera does not support it. WebGL report says that it is supported, but disabled. opera://gpu says that it is enabled.




  • @gryt What does says about it? Examples of sites where that message appears?

  • HTML5test says it is supported - but modern Unity WebGL games say it is not supported and WebGL reports state that it is supported, but not enabled.

    I also tried creating a canvas and get the WebGL2 context, but It didn't return a WebGL2 canvas context.


  • You can play with opera://flags/#use-angle to see if it works in one of the non-default modes (restart after changing). Revert to default if it doesn't help.

    You can goto the URL opera://settings/system, disable hardware acceleration, restart and try again.

    You can mask as Chrome to see if it's a browser-detection issue.

    You can try in Opera Developer from to see how things work there. Maybe the newer version of Chromium it uses will help.

    You can see what Vivaldi, Chromium, Brave, the new, Chromium-based Microsoft Edge, and Chrome do.

    You can try opera://flags/#ignore-gpu-blocklist.

  • Changing the use angle to OpenGL fixed it, thanks
