Ok, that stack trace doesn't tell me much as the interesting parameters are optimized out :/
If this was a general bug, I suspect the issue would be present in a lot of places though, so my immediate reaction is to point towards the emulator :) You can compare the buffer size used in uploadBatches() to the offsets and sizes used in the renderMergedBatch() function, but from what I can see, they are all correct.
There is no way to disable optimizations or use the old renderer. The new logic is here to stay.
cheers,
Gunnar

Emne: Re: [Development] New SceneGraph related issue
I got stracktrace. It is as you predicted glDrwaElements. Is there any possibility to make some kind of workaround patch to make it work on emulator (I suppose it is emulator GL issue), perhabs by turning off some optimizations and so on? I would like to add such patch to rpm emulator package until problem will be fixed.
