I've submitted a patch to Wine to throttle our calls to XResetScreenSaver to
once every five seconds: https://source.winehq.org/patches/data/169958
However, I'd argue our previous behavior isn't obviously wrong. What we were
doing was calling XResetScreenSaver each time we received user input on a
joystick in order to delay the screensaver coming up despite no keyboard/mouse
input. It's not obvious that this behavior was incorrect. Are you sure you
shouldn't be able to handle this behavior from a client?
