The issue was specifically with seeing mode changes from other processes. The test calls `EnumDisplaySettings()` in a loop waiting for the expected mode change. If we don't process `RRNotify` events in `xrandr14_get_id()` we won't see the new mode until some thread processes the messages. Since there are no such threads in the test process, the test will fail.
