Strange waveform graphic

[steve0916]

I'm running a session in 5.2 beta. I'm recording 2 tracks of acoustic guitar simultaneously, mic'd and direct. I haven't seen this happen until tonight and have been working on this for a few days now. I did a destructive punch in on a selected section and occasionaly the waveforms are coming out screwy. The top of the 2 tracks is my direct signal and that is coming out as 3 boxes of different sizes on top of the median line, the bottom of the 2 is my mic'd track and that's coming out just flatlined as if there isn't any audio at all on it. When I listen to the tracks they sound fine and when I zoom in about 2 or 3 times (I'm originating at the time in seconds right before the milisecond readout), the waveform comes back. When I zoom back out again I see the strange graphic. I recorded on top of that again and I had my regular waveforms back, then a few times later back to the same weird graphic. Has anyone else had this issue yet?

In the region bin select the regions and rebuild their overviews.

I'd also run a disk utility to see if you have any drive problems.
