ColumnPane has black background
The ColumnPane shows only the first 2 rows correctly. All others are black. When clicking on a cell it gets readable. Also the checkbox is missing until you click on the cell (see row 3). It worked in 3.8, but due to another bug in the ColumnPane, I updated to version 3.9
Refreshing the control or the form does not change anything
Thanks, we will check for this
