Not OP nor maintainer, but I cannot reproduce on Version 1.10.0, which seems to have rewritten a lot of the directory diff code. Running `kdiff3 folder1 folder2` shows a folder diff view as expected. Can you verify?

Moving to needs info as the final result window should indeed show. Are you not even seeing this for short files. I ask because kdiff3 has known situation where it fails to show the progress GUI but runs just the same if launched via context menu in linux.

Using https://download.kde.org/stable/kdiff3/kdiff3-1.10.0-windows-cl-64.exe

Still seeing this bug. I.e. when launching "kdiff3.exe folder1 folder2" for large folders the progress GUI is not shown at all. And after some minutes the main window appears.
