Now it's only called if textureData != nullptr - the unpack buffer should be set to nullptr - the texture data base address should be obtained based on the plane of the texture https://developer.apple.com/documentation/iosurface/1419379-iosurfacegetbaseaddressofplane?language=objc 1688852 1 kbr 2020-09-15 14:27:44 -0700 Thanks for uncovering these issues Kimmo. Do you plan to take this? I see I left a few TODOs in ANGLE's src/libANGLE/renderer/gl/eagl/IOSurfaceSurfaceEAGL.mm . 1690801 2 webkit-bug-importer 2020-09-22 12:00:28 -0700 <rdar://problem/69384081> 1890508 3 kkinnunen 2022-08-11 00:00:18 -0700 EAGL is not supported anymore, closing
