You're right, please change this line to   

InvalidateRect(GetHeaderRect(), FALSE);

and build library.

Please, let me know if it fixed some flickers for you.

 

I'm trying to track down a flicker problem with tab controls using skins.  the problem is this code in XTPSkinObjectTab.cpp

 

void CXTPSkinObjectTab::OnMouseMove(UINT /*nFlags*/, CPoint point)
{
 int nHotItem = -1;
 CTabCtrl* pTabCtrl = (CTabCtrl*)this;

 for (int iItem = 0; iItem < pTabCtrl->GetItemCount(); ++iItem)
 {
  CRect rcItem;
  pTabCtrl->GetItemRect(iItem, &rcItem);
  if (rcItem.PtInRect(point))
  {
   nHotItem = iItem;
   break;
  }
 }

 if (nHotItem != m_nHotItem)
 {
  m_nHotItem = nHotItem;
  Invalidate(FALSE);

  if (m_nHotItem != -1)
  {
   TRACKMOUSEEVENT tme = {sizeof(TRACKMOUSEEVENT), TME_LEAVE, m_hWnd, HOVER_DEFAULT};
   _TrackMouseEvent(&tme);
  }
 }
}

the call to Invalidate redraws the whole tab, so when you mouse over the tab items at the top, the whole tab redraws twice whenever you move from hovering over one tab item to another even though you didn't click the mouse.

 

the call to Invalidate should be a call to InvalidateRect, and should include a rect specifying the update region of the tab items affected (the 2 changing state), not the entire control.
