iOS not receiving touchEvent at app start up

SGaist

Might be, note that both platforms have different backend.

Could you also test with Qt 5.7.0 ? That way it could help pinpoint whether it's something new to 5.7.1.

@SGaist I noticed that. That is the difference between platform plugin ios and cocoa.

I still haven't got to the bottom of the problem but instead I switched my "platform_window_opengl" to use QOpenGLWindow. That code path fixes the problem. I still don't need to pull in the widget library (don't need/use it) so for now I'm happy.

When I get a chance I'll dig into the implementation of QOpenGLWindow vs QWindow (with own context creation) to see what functionality is missing.

Does it still sound worthy of bug repoting to you?

SGaist

Yes please. Even if the recommended way to build mobile UI is QML, it's better to have that kind of stuff known.

@SGaist I've tested with 5.7.1 and 5.8. I'm very sorry but as a solo developer I don't (at the moment) have time to run those sort of regressions.

@SGaist I've got weird and horrible news.

I let my iPhone update to 10.2 (from 9.3) last night and now the problem doesn't occur!

These sort of things make me go... ARGH!

SGaist

@matthew-kuiash sure thing, I understand. Ok, so there was something going on with 9.3. I think it's still worth mentioning.

@Rameshguru Please don't highjack other people threads with completely unrelated questions, open your own threads.

Since it's C# related, go to General and Desktop. On the top left there's a big blue button call New Topic.
