Hi

I am currently working on migrating a browser application from Qt5 to Qt6. I am using a hw kernel on an Intel Core i3-12100 processor.

Recently, I encountered an issue where the application freezes completely after a few click or keyboard events, accompanied by the following warning:

`[init -> wm] Warning: input overflow - resetting queue`

Any insights into why this error occurs and how to resolve it would be greatly appreciated.

Thanks

The error message is a direct consequence of your application freezing. The wm window manager passes user-input events to its clients. If the wm client does not collect the events in the Qt event loop before the server-local queue is full, the server emits this warning and resets the queue. This way, a temporarily stuck client could later pick-up the most recent events addressing its windows.

Unfortunately, I don’t have any idea, why your application freezes outside the Qt event loop.

Yes, you’re right. I was looking at the issue the other way around and initially thought that the full event queue was causing the deadlock, whereas the full queue was actually a consequence of the deadlock.

I found and fixed the underlying issue. Thanks for the explanation!
