There appears to be some sort of problem with gui-lib in Racket v6.9 that isn't apparent in v6.8. In my image viewer program Ivy[1], moving from one image to the next takes a few seconds even for small images and if I click in a text-field with lots of text in it, it'll take a half second for the cursor to update its position. Highlighting text will take a similar amount of time to take effect. These problems don't seem to appear on Windows, so I think it has something to do with the Gtk+3 innards, but I couldn't even begin to say what could be the reason. I was confused for a little bit, but downgrading to Racket v6.8 seemed to fix all the problems I listed earlier. Things seem much more snappy than when the program is using Racket v6.9.
P.S. I'm running amd64 Gentoo [1] https://github.com/lehitoskin/ivy -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
