Print Page - [CLOSED] VSync doesn't work when minimized

Title: [CLOSED] VSync doesn't work when minimized - Windows
Post by: oskar on August 02, 2012, 17:26:49

Problem

When I minimize the LWJGL display, the frame rate is no longer capped to 60 frames-per-second with VSync enabled.

How To Reproduce

I wrote the following code that should trigger the bug.

Code Select


Display.setVSyncEnabled(true);           
try {                                    
    Display.create();                    
} catch (LWJGLException e) {             
    e.printStackTrace();  
}                                        
while (!Display.isCloseRequested()) {    
    Display.update();                    
}                                        
Display.destroy();

Environment

Java Version: 1.7.0_02
Operating System: Windows 7 x64
LWJGL Version: 2.8.4

I'm surprised you would expect that to work. The thing you probably want to do is to check Display.isActive() and if it returns false, just sleep for 30ms or something.

I did expect it to work. Is it then not a bug? Thanks for the suggested fix.

It is indeed not a bug - if the window is minimised there's no display to vsync to.
