Problem with creating a window using GLFW (LWJGL)
问题
我正在尝试使用GLFW创建一个窗口。窗口已经创建，但在尝试几次后，在窗口创建之前需要等待很长时间。
这里是我正在使用的代码：
import org.lwjgl.glfw.GLFWVidMode;
import org.lwjgl.opengl.GL;
import static org.lwjgl.opengl.GL11.*;
import static org.lwjgl.glfw.GLFW.*;
public class Main {
public static void main(String[] args) {
System.out.println("0");
if (!glfwInit()) {
throw new IllegalStateException("GLFW couldn't be initialized!");
}
System.out.println("1");
long window = glfwCreateWindow(450, 800, "Test #1", 0, 0);
if (window == 0) {
throw new IllegalStateException("GLFW failed to create a window!");
}
System.out.println("2");
GLFWVidMode videoMode = glfwGetVideoMode(glfwGetPrimaryMonitor());
glfwSetWindowPos(window, (videoMode.width() - 450) / 2, (videoMode.height() - 800) / 2);
glfwMakeContextCurrent(window);
GL.createCapabilities();
float i = 2;
float speed = 1;
System.out.println("3");
while (!glfwWindowShouldClose(window)) {
if (i > 253 || i < 1)
speed *= -1;
i += speed;
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_QUADS);
glColor4f(0.38f, (i % 255) / 255, (i % 255) / 255, 1.0f);
glVertex2f(-0.5f, 0.5f);
glVertex2f(0.5f, 0.5f);
glVertex2f(0.5f, -0.5f);
glVertex2f(-0.5f, -0.5f);
glEnd();
glfwSwapBuffers(window);
glfwPollEvents();
}
System.out.println("4");
glfwDestroyWindow(window);
glfwTerminate();
System.out.println("5");
}
}
程序的输出是
0
//现在要等很长时间

看起来似乎需要很长时间来初始化GLFW，但我不知道如何修复它。

I'm trying to create a window using GLFW. Window IS created,
but after a few attempts it takes really long before window is created.

I can't find any solution for this and don't know what can this be caused by.
Here's a code I am using:
import org.lwjgl.glfw.GLFWVidMode;
import org.lwjgl.opengl.GL;
import static org.lwjgl.opengl.GL11.*;
import static org.lwjgl.glfw.GLFW.*;
public class Main {
public static void main(String[] args) {
System.out.println("0");
if(!glfwInit()) {
throw new IllegalStateException("GLFW couldn't be initialized!");
}
System.out.println("1");
long window = glfwCreateWindow(450,800,"Test #1",0,0);
if(window == 0) {
throw new IllegalStateException("GLFW failed to create a window!");
}
System.out.println("2");
GLFWVidMode videoMode = glfwGetVideoMode(glfwGetPrimaryMonitor());
glfwSetWindowPos(window,(videoMode.width()-450)/2,(videoMode.height()-800)/2);
glfwMakeContextCurrent(window);
GL.createCapabilities();
float i = 2;
float speed = 1;
System.out.println("3");
while(!glfwWindowShouldClose(window)) {
if(i> 253 || i < 1)
speed *= -1;
i+=speed;
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_QUADS);
glColor4f(0.38f,(i%255)/255,(i%255)/255,1.0f);
glVertex2f(-0.5f,0.5f);
glVertex2f(0.5f,0.5f);
glVertex2f(0.5f, -0.5f);
glVertex2f(-0.5f,-0.5f);
glEnd();
glfwSwapBuffers(window);
glfwPollEvents();
}
System.out.println("4");
glfwDestroyWindow(window);
glfwTerminate();
System.out.println("5");
}
}
Program's output is
0
//Now for a really long time nothing

So it looks like it takes really long to initialize glfw, but I have no idea how to fix it.

经过一些研究，我发现问题与USB输入设备有关 - 在我的情况下是Corsair k55键盘。
根据一些文章和GitHub问题，我了解到这个问题也是由一些其他设备引起的（在许多情况下是Corsair，但不仅限于此）。
解决方法是：
- 找出是哪个设备引起了问题（通过拔掉设备，这是我解决问题的方式）
- 现在（如我发现它是我的k55）我必须更新ICUE（驱动程序）。
希望能帮助到你 
英文:
After some research I found out, that the problem was related to USB Input Device - in my case - Corsair k55 keyboard.
From some articles and github issues I learend, that that bug is also caused by some other devices (In many cases Corsair, but not only).
The fix is:
- to find out which device causes the bug (by unpluging, that's how I did)
- now (as I found it's my k55) I had to update ICUE (drivers).
Hope it helps
