Description Matt Hutchinson 2020-09-01 05:29:25 PDT

Device: iPad Air 2
OS: iPadOS 14.0 (18A5357e)

Issue: All webGL content is broken. Have tried:
https://get.webgl.org/
https://webglsamples.org/

Console shows multiple errors such as:

WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost
WebGL: INVALID_OPERATION: texParameter: no texture

(I have had reports that the above content does work on an iPad Pro)

Thank you for the report! Looks like Apple is tracking this internally already, but this information helps.

Could you please clarify if this worked in previous betas?

Could you please confirm what the situation in 14.2 release is? I do not have this model to check with.

Hi I can confirm that this issue was not present in the 14.2 release

Thanks
