Hi! Thanks for posting. I've recently started helping World Machine as Community Liaison, so will periodically pop into forums / support tickets.
Yes, that's one of the bugs we're currently trying to track down and resolve. If all goes well and we can figure out why that's happening, we'll put out a bug-fix in the coming weeks that resolves the issue. Crossing my fingers but yep, absolutely working on it!
I know this issue has been brought up before on the forums, but drawing lines with the layout generator renders use of WM completely unusable. When trying to draw the line(s), or manipulate the line(s), the system slows to a crawl.
My computer is running the latest build of Windows 10, Intel 5960 (8 core), 64GB of RAM and (4) Titan X Pascals.
Can you please update us with some information on whether, or not this can, or will be addressed?
