Pbuffer.getCapabilities causes segfault on some Windows machines in fullscreen

[Zarkonnen]

Minimum reproduction code:

Display.setFullscreen(true);
Display.create();
Pbuffer.getCapabilities();
Display.update();

Result:

A fatal error has been detected by the Java Runtime Environment:
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000007fed7a082f9, pid=7296, tid=6796
Java frames: (J=compiled Java code, j=interpreted, Vv=VM code)
j  org.lwjgl.opengl.WindowsContextImplementation.nSwapBuffers(Ljava/nio/ByteBuffer;)V+0

j  org.lwjgl.opengl.Display.swapBuffers()V+39
j  org.lwjgl.opengl.Display.update(Z)V+44
j  org.lwjgl.opengl.Display.update()V+1

Note that the crash is caused by Pbuffer.getCapabilities but happens at Display.update.

This only happens on some windows machines, and only in fullscreen, but is reliably reproducible there. The machine I have that has this problem has the following specs:

• HP ProBook 4540s
• Windows 7
• AMD Radeon 7650M and Intel HD Graphics 3000 with up-to-date drivers

Let me know if you need further information!

I cannot reproduce this and it sounds a lot like a driver bug. Does the example code crash with either GPU? Does adding -Dorg.lwjgl.util.Debug=true produce any output?

[Zarkonnen]

The bug only affect some machines, yeah. I have a similar machine where it doesn't happen, but I also have a handful of reports from other people that it happens on theirs.

The example code doesn't work if I turn off the Radeon, which isn't too surprising.

Running it with Debug=true gives the following debug statements before the crash:
