JoGL Display list problem

Hello everyone,

I have a weird problem with jogl beta (the latest beta build, beta05). I have a scene with some models init and each model is a separate display list. Everything renders fine on my desktop computer with a geforce 6800 but on my laptop with a ati x600 it just skips some display lists. there is no error, no nothing. it just skips the complete list. so some models are drawn and some are completely not. if i change the code to not using display lists, everything renders fine. it seems that jogl just renders as much as it wants to and then just stops at certain amount of lists. and i’m really sure that i don’t have too much lists, in the test i did just now, there were just 3 lists.
now the funny part: i first thought it was an ati problem, but the problem can also occur on my desktop nvidia. only there it occurs much later, say after having rendered much more display lists.

another one: using jogl 1.1.1 stable removes the problem completely without changing any of the code (just the api differences). unfortunately i want to use the program also on an intel mac und so i’m forced to using the new beta build.

any help is really appreciated, since i’m just stuck with this problem. i’m not new to opengl, i did program a lot of it in c++ and now i have to use it at university with jogl.

Do you have a test case which shows the problem? What OS are you running on which shows the problem?

Are you able to isolate the issue to a particular JSR-231 beta build? JSR-231 beta 4 had a substantial number of changes and beta 5 should in general be more stable than beta 4 due to tracking down some problems introduced with beta 4.

The OS i’m using on both computers is windows xp. right now, i’m using beta5 but i can test it also with beta4. i will post the results later.
the whole case is part of a bigger project and the thing is, that this problem only occurs at a certain amount of polygons. but the project should be opensource, i will have to ask them here at university if i can post it somewhere.
if i can, i will assemble a little test program and upload it.
