If it's hard to see, here's the same skin with a column line width of 32:
I would expect the column lines to actually split the columns, as the skin.ini article on the wiki mentions in the description of ColourColumnLine. This is what that looks like (taken from Lunatic Rave 2):
Alternatively, column lines could be centered between lanes. You could get the above result (column lines pushing lanes apart) by increasing the columnspacing property, or keep it like it is now by keeping the columnspacing at 0.
osu! version
Reproducible with any skin I've tried on b20151217.2 on Mac OS X 10.11. Same on my Windows 10 desktop on cutting edge.
I've tried changing the 'ColumnSpacing' in skin.ini, but this does not work. Column lines are drawn inside the lanes, so adding more space between them does not fix this. I currently added a few pixels of transparency in some of my skin's assets it looks like:
It takes a ton of time to get this right, and even then it's slightly off...
