Yes, it's slow because of these line :

http://lxr.kde.org/source/extragear/graphics/digikam/libs/widgets/common/previewwidget.cpp#839

...which call repaint() on viewport. I don't have found a good solution.

In fact the problem is that Qt4 catch keyboard _release_ event in case of key
are not yet released ! I think to use a timer here to prevent this call if 
keyReleaseEvent is called too shortly. 

Do you understand the problem ?

Gilles
