- if I take the application built and running without this issue with Qt 5.12.5 and replace the DLLs with those from Qt 5.15.0, the issue appears. That means there is a change in the event handling between 5.12.5 and 5.15.0 that causes the issue to appear.
It's super hard telling what might be going wrong without a testcase.I'd anyway start by using 5.15.1/2 (not 0) and actually recompiling the application, just to exclude subtle binary compatibility breaks.
You may also want to inspect the event posting and delivery (e.g. by overriding QCA::notify(); and/or by using ETW tracing; and/or by posting and dispatching your custom "metacall" events instead of using a queued invocation in the same thread).
