OpenGL window stops working after switching tabs #588

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
If I start the jMonkey SDK, it opens with the tab labelled 'OpenGL window' 
showing and working (it can display the scene or the terrain for editing).  If 
I then switch to another tab and back to the OpenGL Window I find that it no 
longer works.  The window is grey and doesn't change if I attempt to edit the 
scene.

(To be completely clear, because I know how annoying vague bug reports are, 
most of the jMonkey window still works as normal.  I can see the project 
browser on the left, the application output at the bottom, and so on.  However, 
the OpenGL Window tab is grey and displays nothing useful.)

I am running Ubuntu 12.04 64-bit with the proprietary nVidia display drivers; 
specifically the version which is installed by Steam (nvidia-experimental-310 
version 310.14-0ubuntu0.3).  I am also running the newer kernel, 
linux-image-3.5.0-26-generic version 3.5.0-26.42~precise1.  Given that most 
jMonkey users don't seem to be affected by this problem, I suspect that the 
problem may be specific to Linux or this nVidia driver.

By the way, jMonkey-based games seem to work fine.
