Dual monitor issues

I am starting to debug my code on dual monitors, but I see lots of different issues. For example, one JOGL application reports an FPS of 1000, although the screen image is not updated, and I am supposedly using vsynch (gl.setSwapInterval(1)).

Another application either fails to display or alternately fails to draw text or sets gl.glClearColor() incorrectly.

I'm running GLCanvas in a Frame, and running it as a windows application - I don't need full screen and I don't need dual monitors. Obviously i need to not crash if a user has dual monitors. I've seen the issues on both Linux 64-bit and Vista 32-bit.

Are there any dual monitor gotchas I should know of?

As this is a utility that is not meant to run in a multitasking environment, I'm tempted to just detect multiple monitors using...

GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice[] gs = ge.getScreenDevices();

...and ask them to switch one off :-)

EDIT: While testing my crude 'please switch off the second monitor!!!' code, I found that if I start the application with one monitor, and then change to two monitors, everything works correctly, on Vista-32 anyway. The apps run correctly. I can even drag the JOGL windows to the secondary monitor and they display fine. I can have multiple JOGL windows open simultaneously on both monitors.

Hi

Which version of JOGL do you use? Do you have the same problem with GLJPanel? Does your problem happen only when you move the frame from a monitor to another one?

Hi,

Thanks!

I will try with GLPanel tonight hopefully, and update this with the other information you are asking for.

The problem occurs when a window opens - it is not related to moving the window between screens.

Regards,

Agnes

EDIT: I haven't had time yet to get back to this issue, and in the short term i have just resorted to detecting dual screens and giving a warning.

By the way, I'm running this version:

 Implementation-Build = 2.0-b709-20130720
