javascript - WebGL JavaScript 游戏在 Chrome 中导致 STATUS_ACCESS_VIOLATION

Question

我正在使用 WebGL 开发 HTML5 游戏，在 Edge 和 Chrome 上运行它时遇到了这个奇怪的问题。页面将随机转到“Aw，Snap！” 状态为 STATUS_ACCESS_VIOLATION 的错误页面，让我完全退出。我推断这不是由于游戏中的任何特定状态，因为它会在任何位置的任何时间后随机发生，所以我能想到的唯一常见线程是使用 WebGL 时。

我使用 WinDbg 分析了 Chrome 转储文件，发现错误状态列为“0xc0000005 - 0x%p 处的指令引用了 0x%p 处的内存。内存不能为 %s。” 我的着色器会导致这种情况吗？如果这是一个 JavaScript 问题，我想我会在控制台中看到它，并且它不会使整个页面崩溃。我在网上找不到任何可能导致此问题的具体信息，更不用说如何缩小代码中的问题范围了。这是我的着色器代码和转储信息。

顶点着色器：

attribute vec2 a_position;
attribute vec2 a_texcoord;

uniform mat3 u_positionMatrix;
uniform mat3 u_textureMatrix;
varying vec2 v_texcoord;

void main() {
    gl_Position = vec4((u_positionMatrix*vec3(a_position,1)).xy,0,1);
    v_texcoord = (u_textureMatrix*vec3(a_texcoord,1.0)).xy;
}

片段着色器：

precision mediump float;

uniform sampler2D u_texture;
uniform vec4 u_blend;
varying vec2 v_texcoord;

void main() {
    gl_FragColor = texture2D(u_texture,v_texcoord)*u_blend;
}`);

转储分析：

什么甚至会导致这种情况发生？我正在运行 Windows 10 并通过本地网络服务器访问游戏。这也发生在我的手机上运行游戏。这种崩溃不会在 Firefox 中发生。这可能与我的计算机或我的着色器有关，或者哪种 JavaScript 实践可能导致这样的事情？
