I'm curious what the reasons are since it wasn't really explained in the check-in comments. I've been running with my patch now for 3 months and haven't seen any visual oddities. But perhaps my anti-aliasing settings are masking what the original change was for... >> So I don't think this is the right way to fix this bug.

This does fix the descenders being chopped off, but ends up making the block cursor not cover the whole glyph it's highlighting--it's really ugly. Any idea if we'll get a real fix (or one our workarounds) into CVS before emacs 23.1 is released? -David
