Update 28.07.2011:
After the release of 6.0.3 we detected that there is a performance issue with the new grid overlay feature in Cubase 6.0.3 under Mac OS X (> Cubase under Windows is not affected> ). Currently the only workaround is to disable the grid overlay (what a pity, now that it’s finally here). This can be achieved by turning the intensity slider (Preferences > Event Display section) entirely to the left. We aim to resolve this issue ASAP.
Sadly this is not true.
I experienced several screen redraw issues.
Most prominent, when in play mode with Stationary Cursors active and the mouse switched to scissors.
If I now move the mouse, the screen completely freezes.
The tested projects have a lenght of 20 min up to 2 hours.
I also found, that the redraw jerkiness, depends on what is shown on the screen.
If I scroll down to where are mostly Group and FX tracks ( i.e. tracks with no events ),
it gets worse.
A few others also noticed this ( apparently with longer projects )
Can anyone from Steinberg repro ?
