I successfully built MITK 2016.03.0 on Mac (Yosemite10.10.5). The windows in QmitkStdMultiWidget look good in MitkWorkbench, but when I run MitkStep2-8 in the tutorial, there is an display issue. For each window, actually only the left-bottom quarter is used for rendering, while mouse events are still based on the whole window. Did anyone also have this issue? I guess there is some difference between MitkWorkbench and MitkSteps on using QmitkStdMultiWidget/QmitkRenderWindow. Can I get some help on this issue?
