Image.getGraphics（）导致崩溃

Question

Whenever I use the method getGraphics() from org.newdawn.slick.Image in fullscreen mode, it causes a crash. It works perfectly fine in windowed mode, and I've tried doing stuff like Graphics g = new Image(100,100).getGraphics() , this also causes the crash.

I am using Slick2D

This is the output I get:

I've tried different images, different resolutions, different framerates, etc. but nothing works when in fullscreen.

I've tried updating my drivers but with no luck!

I think the problem is just your GPU is being overloaded when you try to save the screen as an image.

A bit of digging around online suggests you might be working with a computer that uses an lightweight (and low power consuming) integrated GPU for most tasks and is supposed to switch over to a dedicated GPU for things like gaming. The problem then is that your Slick2D game is not triggering the switch from the integrated GPU over to the dedicated GPU.

You can read a bit more in this thread for another Java game:

The solution suggested is to tell Nvidia to use the dedicated GPU for your Java application.
