Improve the system (usually Xorg) load by increasing the wait time between redraws

The time to wait is set to the time between pings but restricted to a range between
0.03 seconds as a minimum (this was the fixed wait time before this patch) and
0.20 seconds as a maximum (needed to increase the size of the red bars in case
of no response and to redraw the window content in case of window resize or similar)
