скриншот

Если мы подключены к серверу, при наведении кнопкой мыши на виджет "ОК" окно приложения не разворачиваются. Прикрепил скриншот.

Если зайти в settings и удалить сервер из спика то происходит аварийная остановка.

qt.qpa.xcb: QXcbConnection: XCB error: 3 (BadWindow), sequence: 1376, resource id: 10513585, major code: 40 (TranslateCoords), minor code: 0
Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt.
You must not let any exception whatsoever propagate through Qt code.
If that is not possible, in Qt 5 you must at least reimplement
QCoreApplication::notify() and catch all exceptions there.
