Hi Daniel, I would have hinted you at the Qt application flags but you are already familiar with them obviously. :-) Maybe someone else have an idea. I believe that the click-offset is something that I saw in a Phabricator task but it must be very long ago. Regarding the VTK base class changes of QmitkRenderWindow: That's mainly because of API-changes in VTK 9 compared to VTK 8. That being said, I guess the newer VTK version could also play an important role here.

Great to see this happen! I have a problem currently with my customized workbench based on the 2018.04.2 release. I see that the new release workbench does not exhibit the problem, so perhaps you also encountered and fixed it. The problem is about high resolution displays that I see in newer laptops. Without changing anything to the code, Qt renders all buttons very small (same pixel size but tiny real size because of the high resolution). I found and option "QGuiApplication::setAttribute(Qt::AA_EnableHighDpiScaling, true);" and an environment variable QT_SCREEN_SCALE_FACTORS to help "old" applications scale nicely. I am using the environment variable. When doing so the application looks nice, but I get an offset when clicking inside 2D render windows. You click somewhere but the crosshair is then positioned a good portion away from the clicked position. My questions: - did you observe this behavior? - did you change anything to the code to handle this? - I noticed you changed the VTK Qt render window in QmitkRenderWindow. Is this related / required / ..? Any thought on this are highly appreciated.
