            Bug ID: 197900
           Summary: Please support WEBGL_compressed_texture_etc1 extension
                    (and possibly WEBGL_compressed_texture_etc too)
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: All
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
          Assignee: webkit-unassigned at lists.webkit.org

Per WebGL WG face-to-face meeting from May 14, 2019:

Could WebKit please expose the ETC compressed texture formats in the WebGL implementation?

This should be easily supportable, and should work on essentially all iOS hardware.

Separately, there was a question of whether WebKit could start using OpenGL ES 3.0 contexts inside its current WebGL implementation. If that's feasible, then it would be easy to also support the ETC2 compressed texture formats and extension:

Thanks!
