我们的代码在 Canvas 上执行非常简单的操作(完全在 UI 线程中):绘制文本、翻译、保存、恢复。
偶尔，我们会得到这个(在运行 4.3 的 Nexus 4 上):
W/Adreno200-ES20(22118): <gl_draw_error_checks:550>: GL_INVALID_OPERATION
D/OpenGLRenderer(22118): GL error from OpenGLRenderer: 0x502
E/OpenGLRenderer(22118): GL_INVALID_OPERATION
并且相应的文本不会绘制到 Canvas 上。
一个问题是它是随机发生的。代码可以正常工作 10-20 次调用，然后会出现此错误，然后在再次出现错误之前再次正常工作 10-20 次调用。
