It is always the same org.lwjgl.opengl.GL1.nglCallList function call at the top of the stack. However the crash not occurs each time. I can't figured out how to reproduce, but it has definitely something to do with list.
Has anybody a clue how can I find the root cause of this problem?
Thx
I'm using LWJGL on 64-bit Linux (Ubuntu) with an ATI graphics card, and I also usually have problems with OpenJDK and IcedTea that doesn't always happen (though it does about 95% of the time). However, I think that my problem is due to a threading issue with the X Windowing system. Beyond that I haven't been able to do anything to fix it.
But if it is some threading problem in X, why does this not occurs using NVIDIA driver, or even mesa? ???
Hmm. I don't know, I haven't been able to really test it that much.
I've just cicked the ATI driver, and started testing with the mesa SGI driver (OpenGL info - Advanced Micro Devices, Inc. Mesa DRI R600 (RV635 9591) 20090101 TCL DRI2 2.1 Mesa 7.10.3).
Since I've replaced the driver I have no crashes at all.
This could be an indicator, that the fish is swimming in the sea of ATI. :P
Hmm. Maybe that's the cause of my bug as well? I ordered a new nVidia card a few days ago, when it gets here maybe that will fix things.
Advice : don't use display lists.
Also : for ATI on Linux, use the open source drivers not the proprietry ones.
Cas :)
why should i avoid display lists?
I thought (I mean the red book writes about :-\ ) it is a good way to gain on performance!?
What are the main drawbacks of display lists?
Off topic:
A curious issue with the open source mesa driver:
On my lenovo with a lenovo 23" display it does not work over the display port, but only over the analogue VGA port! :o
Thx
Display lists are very poorly implemented in most ICDs, often buggy and crashy. I think only Nvidia took them seriously in their prosumer cards.
Cas :)
That's unfortunate, because I find Display Lists extremely useful in their ability to speed up a wide variety of different types of calls. From what I've seen of VBOs and vertex buffers, they only really speed up geometry rendering.
Am I wrong in that? I'm not the most experienced with VBOs/etc.
Yes, you're wrong :) Drivers all operate asynchronously these days batching up commands in a queue anyway. And display lists have all sorts of subtle issues which can break your rendering.
Cas :)
Ah.
Oh well, my current project is fairly heavily based on them and almost finished, so I guess I'll just live with it. Good to keep in mind, though.
