--- Comment #19 from caulier.gil...@gmail.com --- Hi, As i can see in your code : https://github.com/cathaysia/digikamflowplugin/blob/data_loading/src/flowplugin.cpp#L96 https://github.com/cathaysia/digikamflowplugin/blob/data_loading/src/picdialog.hpp#L32 Your CachedLoadThread inherit from ManagedLoadSaveThread. Use PreviewLoadThread instead. it will use the same cache in memory than digiKam core. It will run in a separated thread/core. To calculate the fast loading settings automatically, use PreviewLoadThread::loadFast(). Don't forget to pass a valid size as argument, not zero. I recommend also to host the PreviewLoadThread directly in dialog class, and delete the instance in dialog destructor.
