Restore from sleep to ram fails to restore the the login prompt for password. RACE condition ?

I've used Linux since 1993 (kernel 0.92) and have been using as main desktop for over 25 years. I'm used to fixing issue but this one is hard to figure out.

So if I invoke xfce4 screen lock and screenlock set to suspend to ram, when locked I find when it does suspend then when woken up it appears to start to shows some repetative screen uipdaing but nothing really visable. Tried a few things and no luck.

I then decided to run the screensaver in debug to see if errors, and it nopw works.

The only obvious difference is outputting a debug log but there's no errors ...

LOG="HOME/log/(date '+%Y-%m-%d_%H:%M')_xfce4-screensaver.log"

nohup xfce4-screensaver --debug 2>&1 > $LOG

In normal operation is the wakeup fighting with the shutdown and looping ?

I've used same pm & xfce4 on ubuntu & debian, I finally decided to switch to Alpine linux.
