There's nasty dark stripe (hard to see on a still shot) drawn as well as the black stuff on the right when scrolling. Spring is 0.75b2, map was Tabula v2 and I'm on an nvidia 8800. Anyone else been noticing this?
This is gone when I turn the shadows ingame through /shadows 0 off and it's not related to water reflection either.
I've seen this too, its particularly obvious when zooming out.
I believe its because the shadow map needs to eb reapplied to the map taking into account the new scale but it isn't done in time so you end up beign able to see terrain outside the shadow map hence the shadows.
Large maps are more prone to this issue.
This isn't specific to 0.75b2 either as I saw it in 0.74b2 and it probably lasted a longtime before that too.
