7 years ago @garris Really appreciate for the help. I tried, but seems Capture is not working either. The config is as bellow.
Would you please explain more about the how to use the Capture?
Also, I found an same question raised on Jul 19, 2016: https://github.com/garris/BackstopJS/issues/224
Note: Sorry to tell you that we use the phantomjs as our engine, because the engine - chrome (v62) is not stable in Linux (Centos7), sometimes, for example, it should capture 4 screenshots, but with some possibilities, not all screenshots are captured. Later, we will raise a detail issue to you. Really appreciate for your help in advance.

6 years ago @Kenith I guess @garris meant that with PhantomJS you can only run 1 capture at the time (therefore synchronous), that means asyncCapture is setting only for case when you use Chrome. There is not such setting for PhantomJS.
As for not capturing all screenshots with Chrome engine maybe you will find some helpful answer here https://github.com/garris/BackstopJS/issues/589 ... although I still get empty screenshots even with asyncCapture set to 1 :/

6 years ago @garris If we only can run 1 capture at the time for phantom, you could close ticket. Really appreciate for your help.

Hello All,
We found if we set the engine to phantomJS, the asyncCaptureLimit is not working. Only 1 process is running for capture. Would you please take time for the issue? You are very welcome if something wrong on our side.
ENV: npm - 5.5.1 node - 8.9.1 backstop - 3.0.32 phantomjs - 2.1.1
backstop.json
Thank you, Ken
