X1C fade in affects waveform in weird way

I'm having an issue with X1C where performing a fade in at the beginning of a waveform causes the visual appearance of the waveform to change in an unusual way. It used to be that fades would affect the appearance of the waveform immediately covered by the fade (the audio appears to fade in or out with the fade.) This I understand and like very much. After upgrading to X1C performing a fade now seems to fade all parts of the clip from zero. So with a guitar part, for instance, every part of the clip where I stop playing and start again appears to be fading in from the point where I come in again. It's REALLY strange. So far I don't think this is affecting what I hear, but the new mangled appearance persists through Freeze/Unfreeze, Bounce to Clip, and Regenerate Waveform. Only pulling the fade in back to the very beginning of the clip where the fade becomes non-existent does the appearance of the waveform appear normal again. Anyone else seeing this? Peace, Tunes

I used to have this before X1c and, along with a few other clip oddities, put it down to the AVX problems I had.  These were all caused by the combination of having a Sandy Bridge processor and SP1 of Windows 7 64 installed which introduced the AVX protocols: Sonar code wasn't fully tuned to these.  All this was fixed in X1c and since then I haven't had any of the clip problems, inlcuding the one you're now having.  The fact that you are having this in X1c is worrying, and tells me that this particular one may not be AVX related.  Yes, you need to do a Problem Report for it I'm afraid.
