Waveform draw errors in PT9

[poly915]

When I am navigating on the main edit window, either by clicking in the scroll bars or using the page up/down buttons (or opt+page up/down), often the waveforms will not redraw properly. This is mainly (only?) when I am at a relatively tight room level. When this occurs, I must scroll away from the current screen and then back again to get the wave form to show up properly.

eg. Here is a screen grab of the error

And here is the corrected waveform after I have scrolled 1 screen's worth of distance past and then back again

For me, this is easily reproducible on 3 different computers (all PT 9.0.1 with OS 10.6.6).

Anyone else?

Sorry for the self bump, but this screen redraw bug is getting really annoying for me. Is DigiTechSupt seeing this anywhere else? Are any other users seeing any slow or incomplete redraws on any systems?

Thanks for any input.
