[Interest] Potential causes and debugging tools or techniques for freezes between main thread and render thread

[Nuno Santos]

Hi,

I’m having a very specific and particular problem. I won’t say it is not bad programming on my side but this is are very rare and random issues that usually manifest in the iOS version of an app.

Sometimes the application freezes, probably a deadlock, when the main thread triggers an updated to the window. When I can reproduce this issue, which sometimes is only after 10 minutes of stress testing, the main thread and the render thread are stalled.

I wonder how do I find the cause for this freezes. I’m using version 6.5.3 of Qt for iOS.

Does anyone as any came across similar issues? Any tips?

Thanks in advance!

Best regards,

Nuno
