--- Comment #12 from caulier.gil...@gmail.com ---
I suspect something about OpenGL and video card driver.

Why ? because Face management is relevant of OpenCV library which is... a big
puzzle.
I know already that OpenCL feature in OpenCV is problematic and can lock/crash
digiKam. In AppImage i disable all OpenCV feature that we don't care. The goal
: stability.

Look the cmake configuration options passed to OpenCV :

https://cgit.kde.org/digikam.git/tree/project/bundles/3rdparty/ext_opencv/CMakeLists.txt

All that i can disable, especially the runtime computation optimisations, i do,
as CUDA, DIRECTX, OPENCL.

But for OpenGL, as i know, there is no option (QT_OPENGL is a different stuff
in OpenCV).

So, a good experience is to install a VM (as Virtualbox for ex), and to
reinstall KDE Neon inside, an of course to disable OpenGL and 3D extension with
emulated video card.

It will be interested to see if the memory leak still here.
