Adjust oled gen to fix flashing on timeout (#18747)

Fixes an issue in Ocean Dream that causes flashing after the oled screen
times out and turns off.

This occurs because writing to an OLED screen turns it on as well and we
are both writing then immediately turning the screen off, but only if
the timeout has occurred (no WPM, 30 seconds has passed).
