This problem was debugged on irc yesterday, and the issue was indeed the high dotclock and a non-reduced mode. This samsung monitor reported 1600x1200 normal blanking, while it should use 1600x1200 reduced blanking.
NoRandR had the problem go away trivially, some further poking was required to get RandR to accept the mode.
norandr and specifying "1600x1200R" makes the problem go away for sure.
however, enabling randr still makes the problem appears (admittedly less frequently), even with:
Option "MaxClock" "160"
in the monitor section.
any other method to enable randr while forcing reduced blanking mode?
Option "ForceReduced"
should do the trick. It should work with RandR as well, but you never
know.
