I use Three.js(which uses WebGL) to render the inline video textures in 3D space, it works fine on Chrome, Safari on Mac, and IPhone 6s(IOS 12.1), but got wired issue on IPhoneX(IOS 12.1). By digging into this, the issues seems to be: If there're calls in WebGL: The inline video element that is loading will stop loading until a click on screen, or re-orientate the phone. The inline video texture is not able to update to WebGl when using `texImage2D`(it keeps black, while the video element itself is playing well), only get updated until a click on screen, or re-orientate the phone. The inline video texture is not firing "ended" event until a click on screen, or re-orientate the phone. 1485302 1 webkit-bug-importer 2018-12-05 10:44:47 -0800 <rdar://problem/46492260> 1485380 2 jonlee 2018-12-05 12:46:27 -0800 Is this a regression against older iOS? 1485482 3 larrylin28 2018-12-05 15:44:24 -0800 Iphone6 with same OS(12.1) works just fine 1487183 4 larrylin28 2018-12-12 06:49:34 -0800 Any update on this? 1487232 5 jer.noble 2018-12-12 09:16:39 -0800 Larry, do you have a publicly available reproduction case we can link to?
