I am having the same issue with STM32CubeMX 4.23.0 that I had with the previous version. Having upgraded to Ubuntu 17.10 I can't select the ok button to set my Project settings in CubeMX. Any ideas on how I can select the ok button, key combinations etc ? I have tried resolution changes different ways to scroll but nothing works. Could the designers of Cubemx please make the project settings dialog of future versions resizable ?
