Re: [racket-users] long (16s) pauses in UI associated with OS X, possibly app nap?

One thing that might help is if, during the pause, you open up a terminal, figure out the pid for the drracket's misbehaving and then do "kill -SIGINT " you might get a message with a stack in it. I'm not completely sure about this, but if you start up from the shell (not using "open" but by

Re: [racket-users] long (16s) pauses in UI associated with OS X, possibly app nap?

I gave that file a try with background expansion on and didn't seem to be able to trigger the issue. Background expansion doesn't really interact with the GUI itself unless the little colored bubble in the corner is the lighter purple color (the dark blue and the darker purple both correspond to

I don't see for that file. If I remember correctly it happened in this file: https://github.com/soegaard/urlang/blob/master/urlang.rkt I can't reproduce it now though (which btw is the reason I didn't report a bug). Hmm. Maybe it went away when I disabled background expansion? That file is very

That sounds like something that is fixable and it would be helpful to have a file that exhibits particularly bad problems in order to make sure it really is fixed. I tried opening drracket/private/unit (using "Open Require Path...") and wasn't able to provoke the bad behavior. Do you (or Jens

FWIW I may have seen the same thing. I am not using "automatic parentheses" though. I have seen it at occasion when typing a " in longish files (>1500 lines). This was on version 6.3 (or earlier?). 2016-02-22 21:04 GMT+01:00 'John Clements' via Racket Users < racket-users@googlegroups.com>: > I

I have several students who are observing truly impressive UI delays in using DrRacket. Specifically, it often happens when they type a double-quote (“) with “automatic parentheses” enabled, and after typing the key, it will take more than 16 seconds for the screen to update and for the quotes
