I've got the same problem as in this post but under Linux:http://lwjgl.org/forum/index.php?topic=2661.0
It works on Windows and Mac but the canvas flickers in its background color on Linux. I'm using the latest version of LWJGL.
The post above is rather old so I though maybe some more light has been shed on this lately? Are there any known fixes?
It's probably due to funky hardware and graphics drivers but I'd still like to get it working on older laptops and budget onboard graphics hardware if possible.
