Doing it now - in fact I have just fixed it (I think) so expect an SVN update shortly.
Edit - ...and done. SVN rev 3255.
I am now done for V25 release so far as I know (only remaining serious reported issue I am aware of that has been reported is terrain revealing left behind after going into WB, but I can't reproduce it)


I as well am done for V25, so we can most likely release tonight, assuming nothing major pops up before then.
Edit: It didn't work, here are two screens of it, the first right after I revealed the tiles, the second after I do a viewport shift. I'm using SVN 3255.
Edit2: Here are some other artifacts still present (still on SVN 3255) in pics 3 and 4. If it matters, I am using a 75 by 50 viewport with a focus value of 2.
