Created attachment 121368 [details] Screenshot, which demonstrates the issue; Source: https://pointieststick.com/2019/07/06/kde-usability-productivity-week-78/ SUMMARY With the latest version of Konsole's split you can drag and drop sub windows. A highlighted shows the new position. However, the highlighted area does not match the one of the actual occupation afterwards. If it's a half, it should a hald and not a third. Please compare the screen record.
This should be easy to solve for a horizontal split. A vertical split may need more considerations.
