Sketch Stuttering? Let us help you!

We're currently investigating an issue where Sketch stops responding at regular intervals. Judging from our reports, it started about 10 days ago (June 1st) for no apparent reason that we can think of (our last Sketch update was released on May 11st). We have some hypothesis, but we need your help to fix it since we haven't been able to reproduce it on our test machines.

If you need a quick workaround, keep reading :)

How you can help us determine what's happening

1. Save a system report of an affect machine:

Hold Alt › Click Apple Menu › System Information…

When that opens, choose File › Save and save the .spx file on your desktop:

2. Save the output from Console.app

Open Console.app, select All Messages in the left sidebar, and choose File › Save a Copy As…

3. Save a sample of the process

Open Activity Monitor, and select Sketch:

When Sketch halts, click the gear icon and select Sample Process:

When the operation completes, click the Save… button and save the report:

4. Try to remember what you did to your computer on or around the date Sketch started stuttering

Where by "what you did" we mean things like:

• adding or removing new hardware
• installing / removing software (specially app updates): we have at least one reported case of a rogue Chrome extension halting the system
• modifying your network (things like installing new network equipment, filtering the traffic, etc)
• running unknown commands on the Terminal (maybe you read this article a few days ago and tried some of those sudo commands?)

5. Send us the information!

Take the .spx file from step 1, the .log file from step 2, the .txt file from step 3, and all the info you can think of from step 4, and send them to us via email: mail@bohemiancoding.com

Anything you can remember, anything you can tell us, will help us determine what's going on and fix it on a timely manner.

What you can do while we fix this

If you bought Sketch from Apple's Mac App Store, try downloading the trial from our site: http://bohemiancoding.com/static/download/sketch.zip

It should pick up the license from your App Store version, and so far we haven't had reports of this issue happening with it.

Thanks in advance for your time!

I also have this bug and it is really annoying.
Will send the report in asap.
Sidenote: Sketch also won't remember that I unchecked the onboarding splash screen. I see it everytime the app launches no matter how often I uncheck it.

Sent in a report. Downloaded the non-appstore version from BohemianCoding.com - still having the same issues. :)

I'm experiencing 0 difference after changing builds.

Having same issue with AppStore version. Sent report.

Trial version seems to be working.

I've been plagued by this issue for the last two weeks, but have found a (crappy) solution:

I can solve the problem by disconnecting from the internet. Upon reconnect, Sketch hangs again.

I've correlated the hanging with a process called ocspd. It seems to jump from 30-60% cpu usage when Sketch hangs. Might have nothing to do with it but I know that service is using the network connection to fetch certificate info, so maybe they are correlated?

Will send report via email.

Had the same issue with Sketch 3.3.2 loaded from app store. Same deal with ocspd jumping every 15 seconds or so when using Sketch with internet connection on. If I disconnect from internet there's no stuttering.

Downloaded trial version and there's no stuttering (at least not yet).

Updating from OS X 10.10.2 to 10.10.3 worked for me.
