[PATCH v2 0/1] MR5890: winex11.drv: Fix a possible desktop window message queue hang.

After an X11 event handler queues messages to another thread, TRUE should be returned and eventually propagated to X11DRV_ProcessEvents(). When FALSE is always returned in xrandr14_device_change_handler(), a possible hang can happen for the desktop message queue as follows: 1. The explorer.exe calls GetMessageW() -> NtUserGetMessage() -> wait_objects() -> wait_message(). 2. In wait_message(), user_driver->pProcessEvents() gets called in the desktop window thread to handle RRNotify events and calls xrandr14_device_change_handler() -> display_mode_changed(FALSE) -> send_message(get_desktop_window(), WM_DISPLAYCHANGE, ...) -> desktop_window_proc() -> send_message_timeout() -> send_client_message() -> process_message() -> broadcast_message() -> send_message_timeout() -> send_client_message() -> process_message() -> send_inter_thread_message() -> wait_message_reply() -> a server set_queue_mask() with skip_wait being 1 -> wake_mask and changed_mask are set to 0. 3. In wait_message(), user_driver->pProcessEvents() returns FALSE from xrandr14_device_change_handler(). So wait_message() continues to call NtWaitForMultipleObjects(). 4. Now NtWaitForMultipleObjects() hangs for INFINITE timeout because wake_mask and changed_mask for the message queue are set to 0 so the thread is not woke up. The hang is sensitive to message ordering and only happens in this specific case so it's hard to reproduce with tests. I believe some of the past test timeouts on TestBots can be attributed to this bug. -- v2: winex11.drv: Fix a possible desktop window message queue hang. https://gitlab.winehq.org/wine/wine/-/merge_requests/5890
