Thanks. I am not able to set a date for the release of Alpha 4 – because it depends on so many things. First of all we just need to finish the planned coloring features we are aiming for for Alpha 4. Hopefully we will locate the source of this pixel/garbage/line problem, so we can include a fix in Alpha 4 as well. Others have reported the same issue, so we will do what we can.
A rough guess is a couple of months from now.
Cheers,
Niels
