I commited some changes some weeks ago (not available in 2.4, but they will
be ready for 2.6) that improve the rendering, with less flicker changing
columns width/position. But anyway, would you mind filling a bug report with
a test case? There are different things that can affect the performance of
the ListView, and unfortunately we don't have an universally way to make
fast the ListView (such ListView.SuperFast = true).
If we have a specific usage scenario, we can try to improve the performance
- specially when other users have notified of the bad performance and we
have tuned the performance in the past.
