This happened in scenes with high light count and
with some local light being culled.
The culled lights indices would still be processed
and load undefined data. This undefined data
might be interpreted as a sunlight and go into
the cascade setup loop with an undefined number
of levels.
This created loops of 1 billion iteration per thread
which triggered the TDR on windows.
The fix is to skip the culled light indices.
