Canvas demo causing ubuntu to hang

Hi, I’ve been working on a program that uses the Canvas functionality. It works fine on windows, but I just tried running on Ubuntu 12.10 and whenever I click in the canvas area my mouse pointer disappears and the computer becomes unresponsive. I checked that this also happens with the TestCanvas demo and it does. I’m using the jME 3 RC2 and java-8-oracle. When it happens, I’m unable to use alt-tab, ctrl-alt-del, or anything so I can’t kill it and I have to reboot. Has anyone encountered this or know how to fix it? It only happens with the canvas demo. Other demos I have tried work fine.


Java8? Thats not even in beta, I wouldn’t be surprised if it doesn’t work.

Well I just reverted to Java 7 and the same thing is happening. When I click and drag the view rotates but after about a second of dragging it freezes and I lose all control of the computer.

Yeah, lwjgl has some serious issues on mac and linux atm, we are in the process of moving to jogl due to that.

Cool, thanks for the info
