HI Csaba,

Are you working on the SVN version of the OSG? As the new
StatsHandler additions aren't thread safe yet - I've also seen crashes
when bringing up the scene graph statistics, although not any OpenGL
error report.

Hi Robert,
Ok, then it is a known issue.

FYI, the DrawSerialization was added to improve performance when
running multi-threaded, counter-intuitive it may that be... but
driver/hardware limitations on the PC's with 2 graphics cards + 2 (or
4) outputs I've tested all have show better performance when running
with the draw threads serialized.

Interesting, I'll see what report I get from the fellow who did this:

(and now plans to go for 8 gpus)

Btw, have you seen my other mail in the "infinite block with
CullThreadPerCameraDrawThreadPerContext" topic?
