multiple monitors going to sleep wake as mirrored

I'm not exactly sure if this is the proper classification for this bug, but it seems to fit best. [xfce4-power-manager 1.6.5] Currently I'm running the Xfce spin of Fedora 31.
I have three identical monitors (ASUS VS239) and it seems that whenever they either are put to sleep or switched off (manually, or via the setting in xfce4-power-manager) when they wake, all displays are mirrored. This is noticeable from the lock screen (lightdm-gtk-greeter? using xfce4-screensaver 0.1.8-2 and other screensavers) and persists after logging in. Right now I have a keyboard shortcut set to run an xrandr script as my temporary workaround. After executing this script, windows are unfortunately appearing on whichever display they feel like, along with sometimes being out of ranger (I've been using right-click on the window button for a window and clicking 'move' to bring them back). I also have a profile set in xfce4-settings [4.14.1-2] display that seems to be ignored after unlock.
Locking/unlocking my workstation immediately or in short intervals does not cause a problem. This only happens after enough time passes when the screens actually go to sleep.
Please let me know if I can provide any additional information.
