ttmsfncdatagrid flickering when cells have buttons

hi,
I have a ttmsfncdatagrid in a vcl project and two column must have buttons.
I use the addbuttun for this cells but when moving the mouse over them, there is a lot for flickering and refreshing that can cause exception errors when such a button is pressed and something is changed in the grid/or recreated.
Can we avoid somehow this flickering?
thank you in advance

Can you provide some more info about the steps taken to reproduce the issue?
