I don't see why you have such delay then.. If you have the same problem with the mouse then it's a performance problem. But your GPU ( a 950M ) seems to be alright for Black Ink Ok so the only solution is to give you access to Debug panel for Black Ink ( to have acces to more datas and infos ). If you are agree send an email at email@example.com
In the meantime I got used to it, but it's still there. I kind of forgot about this thread. I don't really have any knowledge of programs and error logs, and there is generally nothing going wrong except the line lagging behind. Does an error log help you guys if there's no error or crash? Just to be sure.
