is it tested with decalbatch ? i'm having an issue : blackscreen after a very short time when i see something. i tried different settings from the simple new Bloom(); to bloom = new Bloom(1024, 1024, true, true, true);
here is my screen code (it's just a simple test, based on decaltest)

I'm using this GL20GroupStrategy viewtopic.php?f=11&t=2732&p=13977&hilit=GL20GroupStrategy#p13994
is it a problem or a conflict ?
Thanks
I don't know how those decals work but I would suggest you to start with minimal test case. If that does not work then its lot simpler to find problem. Usually black screen with openGl is just some openGL state that leaked and really hard to spot.
