Distortion in the new version of LMMS (1.1.0) win 64 bits

Having trouble with LMMS? Ask about it here.
i have a little distortion in the instruments, doesnt metter if is a VST or is a native instrument, i changed all the configuration and continue with the distortion. So i has to re-install the last version (1.0.96 Beta).
i dont know if only happen this in me, or if this have a solution.

Sorry for my english.
Hi again:)
Is this distortion without any outspikes in the mixer a.o. Master visualization?
If you have red curves, or mixer-peaks abowe expedcted levels, then i think i have an explanation, the midi base volume, could be a notch higher in 1.1 -but does it peak out?
