Resizing panes is very slow when there is a lot of text in the output log since it is trying to wrap text as you resize. You could give an option turn of wrapping, but I think just having the panes not resize dynamically would make all resizing more responsive. Since there are number of widgets that could have lots of children or text. Please use something like setOpaqueResize(false) for the QSplitter class.
