Fullscreen in OSweb shows white margins/sliders when exp is in black background
I want to run an experiment that has a black background online with OSweb. However, when I want to run it online in fullscreen mode, the sketchpads are surrounded by white margins (about 1-3cm, depending on the monitor). The exp.is set to be at 1600x900 resolution, and if I make the resolution higher or adjust it according to the monitor (i.e. 1920x1080), instead of margins, there are sliders to scroll a little bit down and up throughout the sketchpad. Hope I managed to explain this right :)
If anyone knows a simple solution to this issue that I might have been missing, please let me know.
