This line has been added, because column headers has not been redrawn under hints in some cases.
It was commented because I was searching a better way to solve a problem and I thought that problem is solved.

I tested with enabling the Application.ProcessMessages. The result was disappointing, because AV’s might occur.
However putting the statement here (near the bottom of the ActivateHint procedure) did not show that averse effect yet.

          AlphaBmp := nil;
        end;
      end;

    Application.ProcessMessages; // Patch for refresh of columns in cxGrid
    Manager.State := hsNormal;
    Manager.FHintPos.x := -1;
{$ELSE}
    inherited;
{$ENDIF}
