Went back in, backed up the fully updated root/usr partition, (only took ~4 minutes on ssd) did reinstall from live media, did not set up wifi or run any updates, issue is present if secondary monitor was set up as only monitor.
if both monitors are configured, issue only happens on secondary (if independent monitor rather than mirror)
if mirror, no issue seen.
kde-wayland does not have this bug... very, very clunky tho.
(how does it go? "...those who ignore the lessons of X11 are destined to reimplement it, badly...")
I still dont see the point of wayland... esp since xorg forked from X11r6.
Interesting tidbit--- install from live media is done booting and at desktop in 24 seconds. (after install/updates)
from traditional media post install boots take ~3x longer, mostly a long wait for networking to come up. for no apparent reason. This off a new ssd in a 2009 vintage laptop.
