>From little experience gained from poking around the Gtk's implementation, I think the EventSenderProxy lacks a method that would reset all the members to their default values before each test is run. Currently the EventSenderProxy is created at TestController initialization and just reused for every test without being reset.

Looking through the Qt's implementation I can see a problem occurring if two subsequent tests happen to click with the same button in the exact same location with not enough timespan between them - this would generate a double click in the second test instead of a simple click. Other similar problems can occur due to no resetting of the EventSenderProxy state.

I'm not saying that's exactly the problem nor do I have any evidence of this actually happening and causing increase in flaky tests. It just seems to me this might be the most possible explanation to the problem due to the flakiness and the fact this started occurring after a test utilizing the EventSender was removed from the test run.
