I noticed a similar problem in the MDI Text Editor sample (straight Debug build, no changes). In my case entire letters are missing.
 
See how the "e" in "parent:file" is totally occluded:

I noticed that when the font is set to Consolas and ClearType rendering is on, I can see that sometimes the last column of pixels of a text block is overdrawn by the next block, cropping round letters:
 
 
The effect disappeared when I changed CXTPSyntaxEditPaintManager::DrawLineText to use ExtTextOut with clipping:
...
CRect rcBGex(nOutCol, /*nTxtBottom - 1 -> */iLine, nOutCol + nTxtWidth, nTxtBottom);
...
pDC->FillSolidRect(&rcBGex, pDC->GetBkColor());
/* pDC->TextOut(nOutCol, iLine, pOutText, nOutTextLen); -> */
pDC->ExtTextOut(nOutCol, iLine, ETO_CLIPPED|ETO_OPAQUE, &rcBGex, pOutText, nOutTextLen, NULL);
