Cascade modules extremely small on 4k screen in 4.18

We were able to reproduce the issue in your first gif, with the problem with the Drag and Drop of the modules in Cascade being off. We do not see the issue related to the different scaling for different tabs however. Was there anything additional you did that made this occur?

We also noticed that disabling the “Enable High DPI Support”, while not an ideal fix, does fix the issue with the Drag and Drop. We’ll get a bug in for the Drag and Drop in the meantime.
