如前所述,在某些情况下,上下文可能会丢失。实际上,WebGL提供了两个事件来表示这种情况,上下文丢失事件(webglcontextlost)和上下文恢复事件(webglcontaxtrestored)。 当上下文事件丢失的时候,由getWebGLContext()函数获得的渲染上下文对象gl就失效了,而之前在gl上的所有操作,入创建缓冲区对象和纹理对象、初始化着色器、...

At first I started getting the error “WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost” and am now getting numerous other WebGL related errors. The errors show at random times after initialization (1min-20min) and opening multiple viewers increases the rate of crashing. GPU usually spi...
Our webgl games crashes "randomly" on machines with intel graphics. My theory is that there is a leak when clearing the stencil with a non 0xff bitmask.Here is what I found so far: Description:The WebGL context is lost and not recovered again, when performing certain stencil buffer ...

As a result, the webGL context may be lost and the browser crashes. The bug has been narrowed down to be inside the Chrome and not from us, more especifically the Angle backend component of Chromium. While we are working on reporting this bug, we have a solution that has proven to ...
那么当遇到播放器报“Too many active WebGL contexts. Oldest context will be lost” 错误时,我们应如何操作呢? 错误说明 这个错误是由于浏览器的限制导致的。 对于每个不同的浏览器: 1、Google Chrome:通常情况下,Chrome的上限是16个WebGL上下文。这是一个相对较低的限制,如果超过这个数量,会出现 “Too many...
