The guidelines are too dark and thick.
I've attached a patch that makes them lighter and more thinner, but still readily visible.

Thanks for the suggestion. The description is limited. Not clear which guidelines in which (sub-)menu are not good. Since this is only cosmetic, if it is not already fixed, this dated bug is set to rejected for now and will be closed.
If any more info becomes available, please, feel free to re-open or send a message.
