runmanager is a graphical user interface (GUI) used to aid the compilation of labscript experiment scripts into hardware instructions to be executed on the hardware. Experiment parameters can be adjusted in the GUI, and lists of parameters can be used to create sequences of experiments, and scan over complex parameter spaces.
I haven't paid enough attention to be able to pinpoint what exact circumstances lead to it, but quite often in qt-runmanager the output box will end up with lots of extra whitespace (well, blackspace I guess!) at the bottom, pushing the printed information to the top of the screen. It seems to be related to changing tabs. It seems to catch up with itself when you get it to sit at the bottom of the scroll bar while a labscript is compiling and spitting out lines to be printed in the box.
