Sketchpad and feedback items are only partially displayed
I created an experiment in OpenSesame which I want to run online via Jatos. When I run the experiment locally, everything is displayed in the way it should be.
However, when I upload it on the jatos server or when I simply use the "test experiement in external browser" option only the lower left corner of the sketchpad and feedback items are displayed (about 75% of the actual item) while text forms are shown normally. A couple of hours ago I did not have this problem, it suddenly started to be displayed in this weird way.
Does anyone know what the problem is and how to fix it?
