Summary: Some state is lost after compositing?
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
URL: https://cvs.khronos.org/svn/repos/registry/trunk/publi

OS/Version: Unspecified
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: WebGL
AssignedTo: webkit-unassigned at lists.webkit.org

This sample demonstrates the issue
https://cvs.khronos.org/svn/repos/registry/trunk/public/webgl/sdk/tests/conformance/misc/delayed-drawing.html
It draws a quad, does a setTimeout of 1000, then issues the draw command again. No state is changed between the first draw command and the second by JavaScript.
Sometime between the two calls 2 things happen
#1) a GL error is generated by code not related to JavaScript
#2) The texture bound to texture unit 0's TEXTURE_2D bind point has changed.
