There are a couple of known issues with anbThemeListView:

• Lots of flickering in Gray or Dark mode when resizing columns or scrolling
• Bizarre rendering

For the flickering, this is very bizarre. We have tried various ways to prevent the flickering, including double buffering, but nothing has worked so far.

There is also a bug in the ListView control that can cause the rendering to appear in bizarre ways. This can include random gaps appearing in rendering or no rows being rendered.

So far, we have been unable to find a resolution for either of these issues, sadly.
