+ccameron: More canvas alpha issues on Mac hablich: We noticed this as well. Thanks for filing. Pretty sure it is a regression. This bug looks like a few bugs we've seen and fixed in the past, so I was surprised to see it even in 59. See issue 658789, and: > issue 666259 , but that should have been fixed in 57. Also similar to issue 648466 , but that was fixed even earlier.

This actually seems to happen with all GPU types on macOS. Initially we thought it was only Intel GPUs. The bug is probably related to handling of the alpha channel for WebGL-rendered canvases. Passing the command line argument --disable-features=WebGLImageChromium, and falling back to the canvas compositing path which renders to a regular 2D texture instead of an IOSurface, works around the problem. Using the new breakpoint on canvas context creation (thanks to the DevTools team -- under "Event Listener Breakpoints" -> "Canvas" -> "Create canvas context", I was able to see the context creation attributes: antialias: false alpha: false depth: true stencil: true The bug must be in the handling of the alpha:false flag when the WebGL canvas is in its own CALayer. I would have thought that maybe the demo was using the premultipliedAlpha flag, but it isn't.

To clarify the issue, which isn't clear from the original post. With WebGLImageChromium turned off, there is no bright overlay [regardless of fullscreen]. With WebGLImageChromium turned on, there is a bright overlay in non-fullscreen. The bright overlay is the bug, not the correct behavior.

Adding the lines:
"""

346 m_stateRestorer->setClearStateDirty();
347 m_gl->ClearColor(0, 0, 0, 1);
348 m_gl->ColorMask(false, false, false, true);
349 m_gl->Clear(GL_COLOR_BUFFER_BIT);

"""
https://cs.chromium.org/chromium/src/third_party/WebKit/Source/platform/graphics/gpu/DrawingBuffer.cpp?type=cs&q=drawingbuffer.cpp+package:%5Echromium$&l=341
fixes the problem. This means that something is modifying the alpha channel of the RGB-emulated IOSurface.

With bajones's help earlier I tried to download a frame of the render - and I got a totally transparent PNG. Maybe there was something wrong with the capture, don't know. #3: I tried playing with the parameters a bit; changing premultipliedAlpha to true or false didn't do anything. #5: Good to know. See also https://codereview.chromium.org/2535173002/ ; maybe I missed a case in that fix? I'll attach a zip of the whole thing in case it's helpful to edit the JS.

Thanks erikchen@ and kainino@ for your analyses. Thinking about this more -- the app is probably doing its own antialiasing, given that it sets "antialias:false" in the context creation attributes. I would guess that it's populating the default WebGL back buffer using BlitFramebuffer from one of its own render targets. Re-reading the spec, this API call bypasses the color mask setting. This may be how a non-1.0 alpha channel is getting set. It's not clear to me how we can best optimize this. Reading CALayer's documentation, simply setting its isOpaque property to true probably doesn't do the right thing if its contents are set to an IOSurface which has an alpha channel and that alpha channel has any values < 1.0. Maybe, in the end, the only way we can make this work in the alpha:false case when RGB IOSurface emulation is enabled is by watching for BlitFramebuffer calls to the default back buffer, and doing the clear of the alpha channel.

Sorry, it doesn't seem to serve up correctly with SimpleHTTPServer - I'm using http-server from npm. Maybe a gzip problem. Played with some more context creation attributes. It doesn't seem to affect the problem, so I have no idea why we don't see this issue anywhere else currently.

Pre-empted by #8. kbr's hypothesis makes sense to me.
,
Mar 9 2017
kbr: Your assessment on CALayer + opacity is correct. It would take more code, but we could also set a dirty-bit when BlitFramebuffer is called, and only clear the alpha channel when someone attempts to read from the texture. This prevents us from hitting the clearing overhead multiple times on repeated calls to BlitFramebuffer. By default I would advocate against this and only try this if we notice the overhead being a problem.

Not really a regression. Unrestricted the view, since there's nothing private in this report.

I thought this would be a straightforward fix, but it turned up spec-level issues that need to be decided upon and resolved. https://codereview.chromium.org/2822743003 is a work in progress which fixes the issue in Chromium, but it's not clear that this BlitFramebuffer call should work at all. It doesn't in Firefox. A conformance test https://github.com/KhronosGroup/WebGL/pull/2368 was just uploaded, but Firefox rejects the BlitFramebuffer call it contains, and so does Chromium when run with --disable-features=WebGLImaegChromium . It even fails if the checks are commented out from GLES2DecoderImpl::DoBlitFramebufferCHROMIUM that would otherwise generate the error "src and dst formats differ for color", so it looks like the OpenGL driver is rejecting an attempt to resolve an RGBA8 renderbuffer to an RGB texture. More study is needed. It's likely the WebGL 2.0 spec will have to be updated to tightly define this behavior and more conformance tests written. Additionally, it seems that the RGBA->RGB emulation currently being done needs to be enhanced to handle this case, since it's visible to the user whether an RGBA or RGB texture/surface is actually being used. In the meantime, Epic seems to have updated their demo so it now renders correctly in Chrome. Therefore downgrading this to P2.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/3d4d5d7a9198bea6f0018a36fc6825637f9a12c4 commit 3d4d5d7a9198bea6f0018a36fc6825637f9a12c4 Author: kbr <kbr@chromium.org> Date: Sat Apr 22 02:09:03 2017 Fix blits from multisampled renderbuffers to alpha:false WebGL back buffer. Blitting from a multisampled RGB8 renderbuffer to an alpha:false WebGL back buffer is supposed to work, and from an RGBA8 renderbuffer is supposed to not work. The emulation of IOSurface-backed RGB textures using RGBA textures didn't handle this case. Add BindTexImage2DWithInternalformatCHROMIUM to the command buffer to allow internal format to be overridden; currently this is only supported on macOS. Use this to bind a second texture to the IOSurface and use it only for BlitFramebuffer calls from WebGL, fixing up the alpha channel afterward. Covered by new conformance test in https://github.com/KhronosGroup/WebGL/pull/2377 .

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/e90ed61ee27f039c110fea16425a723f82bdbaf9 commit e90ed61ee27f039c110fea16425a723f82bdbaf9 Author: kbr <kbr@chromium.org> Date: Tue Apr 25 05:17:22 2017 Fix blits from multisampled renderbuffers to alpha:false WebGL back buffer. (Re-land after fix to avoid deleting nonexistent textures.) Blitting from a multisampled RGB8 renderbuffer to an alpha:false WebGL back buffer is supposed to work, and from an RGBA8 renderbuffer is supposed to not work. The emulation of IOSurface-backed RGB textures using RGBA textures didn't handle this case. Add BindTexImage2DWithInternalformatCHROMIUM to the command buffer to allow internal format to be overridden; currently this is only supported on macOS. Use this to bind a second texture to the IOSurface and use it only for BlitFramebuffer calls from WebGL, fixing up the alpha channel afterward. Covered by new conformance test in https://github.com/KhronosGroup/WebGL/pull/2377 .

On request of a colleague at Apple I've filed Radar 31978831 about this to ask them to reconsider the behavior of GL_RGB type textures backed by IOSurfaces. erikchen@ had previously filed Radar 25691245 in Issue 581777 , which was closed as "working as intended".
