A very good way to get an overall view of the dependency graph of a suite is to use gcylc’s functionality to display dependency graph. This is done using the menu, Suite -> Graph -> Dependencies.
On my Linux box running Ubuntu in the graph display panel texts have very poor constrast against background and so labels are unreadable. However when I move my cursor to within the box of a task or family the background colour and the colour used for the text change, and so labels are clearly legible.
Can someone suggest how I can improve the constrast between texts and background in boxes in the depenency graph display panel without having to move my cursor around?
