The Qt UI continuously redrawing prevents libdecor-gtk's glib dispatch loop
from ever returning since it constantly posts new messages to draw again.
The result is that Moonlight randomly hangs (with the spinner still animating)
at the "Starting app..." phase of connection establishment and never proceeds
until the livelock is broken by loss of focus, hiding the window, or similar.
For posterity, the hanging stack:
