Note: that template is working fine for me locally and I've never seen it fail. So could be more of a Mono/XM issue rather than a template problem. Or the template needs to be updated because a random change broke it. Or it's simply an environment specific issue.
I can not reproduce this locally either.
@Manish Can you try this on other machines? See if it is isolated to just that machine?
@Manish when setting "Is this bug a regression?" to "Yes" please provide the "Last known good build" that you can confirm to work.
If you can't find/provide that then it might not be a regression but something local that affects the results (e.g. different version of macOS or other tools).
I have had several similar reports (screenshots just like your video) with a Xamarin.Mac app using SceneKit. I do not know if it is Xamarin related or just incompatibilities with the original Apple frameworks. When I asked the users that had this problem for their computer specs, the only common thing I noticed was that most of them (all but one) had a NVIDIA 320M graphics card. Have you tried compiling a swift/obj-c based metal sample project on your mac?
We have not received the requested information. If you are still
experiencing this issue please provide all the requested information
and re-open the bug report. Thanks!
