The worst: ImageMagick icon shows four lines of wrapped name/comment in brackets, the last line of which is unreadable as it disappears under the icon below in the grid, so very much not ideal! I'd rather the icon title appeared wider and in a solid colour over the nearby icons when moused over. I'm using a largish font on a small screen (1366x768). Most are OK.
(I have to admit to rarely using the 'Show Apps' or 'nine dots' function, I usually just mash the windows/mod4/super key and type a couple of letters of the name then hit enter)
