That seems to be in this block of code
//use additional convergence speed-up
#ifdef USE_QDM_ASCEND_INTERVAL
if(frac(level*0.5) > EPSILON)
level++;
#elseif USE_QDM_ASCEND_CONST
level++;
#endif
which is a literal copy of what FredB did in urban.frag - the syntax here is
somewhat unfamiliar to me and I don't know precisely what the effect is doing
here - maybe Fred can comment what could be wrong with this?
