I have implemented a Thumbnail view for photos in ClistCtrl with Custom Draw style.
But when there are a lot of items (about 800 or 1000) in it, the items which are selected and unselected (and only these two items) will flicker.
The flicker is more obvious if the selected-unselected items are in the second half of the list. For example: for the first 30 items, I don't see the flicker, but when I scroll the view to the middle -- about 400, it is so obvious already. And it will become worse and worse.
Anybody knows how to solve it?
