ig9icd64中的java异常\访问\冲突崩溃。动态链接到窗口时的动态链接库

Question

当我渲染到一个FBO并将这个FBO blit到窗口，窗口最小化时，Java抛出一个异常\u访问\u冲突异常

这是我的代码，以我的理解，它是做什么的

//Bind the draw framebuffer to the default (0) 
GL30.glBindFramebuffer(GL30.GL_DRAW_FRAMEBUFFER, 0); 
//Bind the read framebuffer to the fbo id
GL30.glBindFramebuffer(GL30.GL_READ_FRAMEBUFFER, frameBufferID); 
//Setting the draw buffer to the screen
GL11.glDrawBuffer(GL11.GL_BACK); 
//Settiing the read buffer to the color attachment of the fbo
GL11.glReadBuffer(GL30.GL_COLOR_ATTACHMENT0);
if(GL30.glCheckFramebufferStatus(GL30.GL_FRAMEBUFFER) == GL30.GL_FRAMEBUFFER_COMPLETE) //Checking if the framebuffer is complete
{ 
  //Blitting the frambuffer to the screen
  GL30.glBlitFramebuffer(0, 0, fboWidth, fboHeight, 0, 0, windowWidth, windowHeight, GL11.GL_COLOR_BUFFER_BIT, GL11.GL_NEAREST); 
}
//Unbinding the framebuffer
GL30.glBindFramebuffer(GL30.GL_FRAMEBUFFER, 0); 

为了防止崩溃，我添加了一个检查来检查窗口是否最小化

if(isWindowIconified) return;
//Bind the draw framebuffer to the default (0) 
GL30.glBindFramebuffer(GL30.GL_DRAW_FRAMEBUFFER, 0); 
//Bind the read framebuffer to the fbo
GL30.glBindFramebuffer(GL30.GL_READ_FRAMEBUFFER, frameBufferID); 
//Setting the draw buffer to the screen
GL11.glDrawBuffer(GL11.GL_BACK);
//Settiing the read buffer to the color attachment of the fbo
GL11.glReadBuffer(GL30.GL_COLOR_ATTACHMENT0); 
if(GL30.glCheckFramebufferStatus(GL30.GL_FRAMEBUFFER) == GL30.GL_FRAMEBUFFER_COMPLETE)
{ 
  //Blitting the frambuffer to the screen
  GL30.glBlitFramebuffer(0, 0, fboWidth, fboHeight, 0, 0, windowWidth, windowHeight, GL11.GL_COLOR_BUFFER_BIT, GL11.GL_NEAREST); 
}
//Unbinding the framebuffer
GL30.glBindFramebuffer(GL30.GL_FRAMEBUFFER, 0);

我还在初始化窗口时添加了这段代码

//Setting the window minimisazion callback
glfwSetWindowIconifyCallback(window, new GLFWWindowIconifyCallbackI() { 
  @Override
  public void invoke(long window, boolean iconified) {
    isWindowIconified = iconified;
  }
});

现在，当我最小化它时，程序不会崩溃，但当我按Windows+D进入桌面时，程序仍然会崩溃

现在回答我的问题： 防止撞车的最佳方法是什么？ 为什么会发生这种情况

如果Java抛出异常\访问\冲突异常，并且它发生在ig9icd64中。这可能是因为您使用的是旧的英特尔GPU驱动程序。我认为这似乎是个问题，因为当我用我的NVIDIA GPU启动程序时它不会发生，而且在我更新我的Intel GPU驱动程序后它也不会崩溃

如果您不确定错误发生在哪里，请在崩溃报告中查找“本机帧：”和“Java帧”。最上面的一行显示错误发生的位置
