Your "<i><b>Maybe you set some resize mode on the headers,</b><b> ...</b></i>" sentence made me try

<div>Without any other details it's impossible to help you.<br>
</div>
<div>Maybe you set some resize mode on the headers, or used a custom delegate that requires too much time to repaint.</div>

<div>We need some actual code to start with, otherwise nobody could help you.</div>

I have a QTableWidget (or QTableView) with 18 columns and about 500 rows.<br>
Now scrolling works without problems, but resizing it is painfully slow. Here is an animation showing the problem:</div>
