As there's no activity on midori forum ,
I'll ask here :

Is there any equivalent for Midori than the about:config

nglayout.initialpaint.delay of Firefox ?

This option display the requested web page only after Firefox downloads and put
together all the content of the web page .

For exemple, a picture will be displayed in 1 time (under a delay of x milli-seconds) and not part by part ...

It's very more REACTIVE with this option and I will be very glad to have the same on Midori

Thanks
