BUG: Custom button is not sized properly

Hi;

I'm using a custom button inside a CXTPReportRecordItemText.
When no horizontal lines are shown in the report control the buttons are correctly drawn.
But when lines are visible, then the button is cut of at the bottom of the row (one px of height is missing)!
See picture below.


Using pButton->SetSize(CSize(x, x)); does not help here. I tried different sizes but the button is always drawn with the current row height in square.
