Red lines THROUGH mispellings and bottoms of words cut off

I have Sigil 0.9.5 on two computers. On one it works fine. On the other the red line under mispellings is through, not under, the words. (screenshot) Also when I first open an individual text file in it, on some of the lines (I'd say about 20%) the bottom halves of the letters are not visible (including the p tags). However, when I click something (like even when I went to take a screenshot) the bottoms reappear.

I'm figuring (hoping) none of this is problematic for the finished .epub, but still it would be nice to correct this. Thanks.
