I am trying to create a slide show type of application where I display images via an ImageView/StackPanel. Every once in a while The screen shows blank and I get an exception in the main application.

java.lang.NullPointerException

I have traced this problem through to the nTexImage2D0 call in com.sun.prism.es2.GLContext.java (549) but that is as far as I can go. The call is returning false and printing out a glerror 0x505 which is out of memory and I believe it is talking about memory in the gpu.

I have created a simple program that causes the issue on my device. I will try to paste it in a comment. If not I can be reached at tom@lemmons.net and can send it to you.
