Just wondering the following... Are the imported transactions related to the open registers ? If you created a new register with a blank transaction, do you see the same delay, just thinking less to draw ? Not sure if you have open aqbanking windows/dialogs open that are covering the register, if you have space can they be moved so there is nothing covering the main Gnucash window, does this make a differnce. If you do have windows/dialogs covering, what type are they, proper windows or dialogs with transient parents, might make a difference.
