Single log period with WINEDEBUG=+x11drv,+server,+relay (wine cf49617c1a3)

Attached another log that focuses on the repeating period, with +relay this
time. One can observe calls to user32.MonitorFromPoint(),
user32.GetMonitorInfoW(), user32.GetForegroundWindow(), user32.ShowWindow().
This looks like Steam is busy-looping in a code path related to window
management and monitors.
