WebGL conformance test fails when alpha=128 |
||
Issue descriptionPlease refer to here for more details: https://github.com/KhronosGroup/WebGL/pull/1527 In particular, the tex(Sub)Image2D fails when the input is ImageData and the alpha channel is 128. This also happens in createImageBitmap() from an image whose alpha channel is 128 (possibly some value that is not 255).
