Newest Fastest Macbook Pro has a serious Simulator display problem

The patched version is from July 18, which is using Xcode 9.4 and the iOS 11.4 SDK which are the latest.

Rob

@Rob, thank you! So, you think it should be okay to use this version to update my existing app or release a new app with the patched version?

Vlad seems to think it’s okay. I’m just confirming that there are not any new iOS/Xcode updates since that release version. I don’t know what was changed or how it affects you. I wish I could be more useful here.

I doubt the change in patched effects builds, but more something that may help keep the simulator from crashing on your MBP.

Rob

My bad. You can use patched to develope. To build your app please use latest daily build.

@Rob, just for clarity, the patch does not prevent Corona from crashing. But instead of a hard crash, the patch brings up the crash in a normal window without taking down the system. So whatever the change is in that patch, it is the difference between causing a hard crash on the Intel graphics models (like mine) and not. Of course, I’m making an educated guess based upon the Intel graphics comments from other contributors to this thread. THANK YOU for your attention to this.

Yes, it is seems to be happening exclusively on new MBP with Intel Iris graphics. Something is bad in driver, which goes wild and corrupts memory, causing crash as a consequence. It is extremely hard to fix, because bug is very random, and seemingly doens’t produce any errors inside the app.

Again, if Patched version works for you, use it for development. But do not submit builds made with it to the Store. Use daily build or public build for that. Like, you can open project and build, right?

@Vlads, myself and one other poster here were able to provide you with 2 examples that cause graphic corruption EVERY TIME. If you solve those corruptions, the crash will probably not occur. Do you need help from us to repost?

Hey guys. I was debugging the issue. Here’s what I want to ask you to do:

  1. Start Simulator

  2. Select Window → View As → Borderless → Windows Phone 480 x 800

   (really, anything without iPhone/iPad in it would do)

  1. Try some other projects

@Vlads, good news and bad news. The good news is that both of the sample projects we provided (a gradient oval and a 3 line text display) are working. The bad news is that my game app still has distorted text and appears to run with the same errors. Per your instructions, I’ve used Windows Phone - 480x800 for these tests.

The primary difference between my game app and the samples is that the game app has considerably more challenging graphics to display. Hope this helps, some.

Did it resolved crashing?

Another thing you can try is to build for macOS.

@Vlads, My app isn’t set to run on Mac and has various plugins that would have to be disabled, and so on. Is it crucial that I spend the time to create a version that will run on Mac?

No, not really. Just as a test.
Hey, [member=‘bc_new_theway’],  [member=‘bmrpeal’],  [member=‘dodi_games’] (and anyone participating here, if I forgot you sorry)

Did you try to run selecting Windows Phone Borderless skin? Or any other non iPhone/iPad skin?

I can see an oval in Windows Phone Borderless skin.

Actually, I can see the right result on all skin except iphone and ipad.

I also build for Mac OS, and I get the oval. But it will randomly make the gpuRestart.

@Vlads, any update on this? Imagine that I can no longer test updates to my App without first installing it on device. An update would be very much appreciated. Meanwhile, I’m advising those that work with me to avoid purchasing any Macbook pro since 2016 with the built-in Intel graphics…ATI Radeon works (according to another developer in this thread)

@troylydon, this is a very complex issue. Vlad is still waiting on some test information as well.

As far as installing to a device being a pain, have you considered live builds? it makes the device like the simulator. When you save in your text editor, the device updates automatically. This really takes a lot of challenge out of device testing.

Rob

@Rob, yes, I understand about the Live Builds. I’ve used it before, so perhaps I need to get it going again. Meanwhile, can I confirm that you now have the laptop and have verified that the two sample projects we sent you do not work - so you have the ability to duplicate the issue? And have you verified the other post from another developer that this only happens on the Intel Graphics MacBook Pros?

Troy, Vlad picked up an MBP that seems to have these failures. I cannot confirm what tests of yours or other developers that he has run or not. Hopefully, he will chime in and answer this for you.

He has said it appears to be a bug with a particular chipset/driver (Intel Iris maybe?) and that it’s not an easy fix.
