I have changed graphics card and this problem is fixed. Looks like the old GT 120 cards don't work with construct 3.

Hurray, that's good news!

I still can't get this working on my mac pro. Nothing at all displayed in the layout screen.

It was working fine until about a week ago, is this something which is likely to be a problem with my graphics card? I can buy a new one if it will fix the problem.

I've just installed iOS 11 to test this but the game jam license has finished. Does anybody else have iOS 11 installed? Would you be able to check if the remote preview is working?

So at the moment I can't really make iOS apps with construct 3? It's a shame, I really love construct but things like this are basically making it impossible for me to use it.

It's not really practical to compile and install the app every time I make a small change and want to see how it works, it would take forever.

Is there any chance this will be fixed in the short term? I've been thinking about paying the subscription but there are so many worrying things like this, still haven't figured out why the layout screen is completely blank on my mac pro either.

So what is the correct way to preview an app on an iPhone / iPad at the moment?

Thanks for the quick reply, here's the chrome://gpu information, webgl2 disabled, is that the problem? I needed an excuse for a new graphics card anyway..

When I open the layout page on construct 3 editor, there is nothing there any more.

It was working fine (although very laggy) on previous versions, could this be a graphics card / chrome problem? I'm on an 8 core mac pro and everything else runs perfectly.

Problems like this are what make me terrified about investing money and time moving my apps over to the browser based program. Does anyone have this same problem?

No luck with changing the plugin versions in XDK...

I've tried disabling the whole event sheet in the app and it still loads to a black screen. The construct loading screen shows up, but then just black. If I close and reopen the app on my iPad it is sort of half loaded up. (Not the sprite font layer or a few images).

If I create a new app with construct it's totally fine, no problems at all. I was hoping to go through the event sheet and re-enable events one by one to find the problem, but it seems even that isn't it.

Does anyone know of anything that might be in my project that is causing it to not load properly?

Thanks for the reply, I'll give that a try... The only thing is that it works fine when I make a new empty app. It's almost like there's something wrong with the app itself that is making it not work.

I'll let you know if I have any success changing the plugin versions!

I have an app which used to work fine, but lately I've been trying to get it to work with wkwebview on iOS.

When I create a simple test app with Construct, I can build it and compile it with cordova and it works fine.

The problem is that my real app just goes to a black screen and nothing happens at all. It must be something in the app causing the problem. One option would be to remake it step by step until I find out what the problem is, but I was wondering if anyone can think of anything obvious that might be wrong?

Thanks!
