TAdvColumnGrid - Selected Row - Dots

Goodmorning,

In the AdvColumnGrid, if a row is selected there are small dots in the corners of the cells.

How can I remove those dots?
I've tried setting the SelectionColor on clNone.
But then the first colomn isn't in the selection color, which gives a strange effect.

Regards.

Cannot be reproduced with grid where goVertLine, goHorzLine = false, goRowSelect = true in grid.Options and iamge added with grid.AddImageIdx()
