It reminds me of this recent comment 
https://bugs.documentfoundation.org/show_bug.cgi?id=158397#c17

"The real problem is in the drawinglayer module. From the following 
debug patch, it is clear to me that 
drawinglayer::processor2d::HitTestProcessor2D::process() actually 
redraws the entire image object on every single mouse event (click or 
move) which, seems very strange when the code in the following debug 
patch is just trying to do a hit test."
