Issue descriptionGoogle Chrome 67.0.3386.0 (Official Build) canary (64-bit) Revision 83a2c341a3999a32a01e268bdb891a56d6edd548-refs/heads/master@{#547395} OS: macOS 10.13.3 What steps will reproduce the problem? (1) Download and unzip this archive: https://drive.google.com/open?id=11FzINUW1s9MAkIiDvR5poBh5Stv0ojIF (2) From the unzipped directory run: python -m SimpleHTTPServer (3) Navigate to: http://localhost:8000/BP_blank4.html What is the expected result? Expect scene to render as in attached screenshot (from Firefox Nightly 61). What happens instead? Scene is blank. From code inspection and from using the SpectorJS extension (in which the scene renders correctly), it looks like the problem may be in the handling of the preserveDrawingBuffer context creation option. This engine uses clearBufferfv and clearBufferfi to clear its color and depth/stencil buffers, and it looks like those APIs don't correctly maintain the DrawingBuffer::buffer_clear_needed_ flag like WebGLRenderingContextBase::ClearIfComposited does.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/a96f5f8168db928f0ac94ee9a4c4f32a6dc8444f commit a96f5f8168db928f0ac94ee9a4c4f32a6dc8444f Author: Kenneth Russell <kbr@chromium.org> Date: Fri Apr 06 04:22:02 2018 Make clearBuffer APIs work with preserveDrawingBuffer:false. The state of which buffers (color, depth, stencil) were modified was not being tracked properly with the introduction of the ES 3.0 / WebGL 2.0 APIs. Generalize DrawingBuffer's tracking, and make these APIs update the state properly. Tested with new WebGL conformance test in https://github.com/KhronosGroup/WebGL/pull/2628 .

Able to reproduce the issue using chrome reported version #67.0.3386.0. Verified the fix on Mac 10.13.3, Win-10 and Ubuntu 14.04 using Chrome version #67.0.3393.0 as per the comment #0. Attaching screen shot for reference. Observed that a scene rendered as in attached screenshot at comment #0. Hence, the fix is working as expected. Adding the verified labels. Thanks...!!
