This is feature frozen. 21.1 Bug fix release wrt 21.1 21.2 The next release with new stuff after 21.0 As people have already written things that should not go into 21.0 there has been a 21.2 branch opened for that. Here they are well separated. The fix in 21.x is that now ascend+descent is used for the height instead of just ascent. As f has no descent there should be ample room for the dots. For instance here 'y' and 'Ä' touch each other so there I could understand a problem. (Just look at the size of the block cursor.) Likewise with 20.4 as it forgot the descent sometimes (which is why the specs were there). Note: Are you sure it was a really a bug that your X server didn't paint outside of the ascend? I don't know what the specs say but it seems pretty difficult to deal with in an interactive environment. Jan
