That is just mathematics, not an issue of "quality" or "strangeness". Usually the speed and behavior of the modulation can be defined in a wide range on any compressor plugin. Some plugins deliberately add additional harmonics/artifacts on purpose to produce certain "color" or simulate certain hardware.

May I attempt to explain myself better.
Below is the analyzer on a 500hz sine wave - no harmonics. Nothing unusual here.
Next is the same 500hz sine wave when I load in an instance of Reaper. Notice that because of compression, the level of the signal is reduced. by about the same amount as reported in the Reacomp Gain reduction display (RED indicator in column).
This is a bit unusual because all compressors, when active should produce some "distortion", which on a sine wave will produce harmonics. All compressors and limiters whenever gain is reduced, will introduce this behavior, to the best of my knowledge... I cannot explain why but they certainly all do, so this was a curious exception. But do read on.
Next - Below is the same sine wave, same settings in Reaper, and the only thing I did to produce this was click on the RMS slider, i.e, no change in settings, just a click without changing any value of the RMS setting.
My expectation. I should not have to click on the RMS slider to get the expected behaviour - to occur. I am kinda surprised that no one else to my knowledge has picked up on this anomaly.
I do wish I could get an explanation of this unanticipated behavior or an admission that this is a bug which needs fixing.
