Windows switching to single monitor after screensaver

Hi. I’m new to Endeavour, having switched from a year of Manjaro and before that over a decade of Ubuntu/Debian systems.

I’m running XFCE for the first time and have noticed a problem with running two monitors. If I have say a web browser running in one monitor and a terminal in the other and the screen save kicks in, only one monitor will ‘wake up’ first and then all windows will relocate to it. The other monitor only seems to wake when I move the mouse over to it.

Is there a way to get both to wake simultaneously or otherwise maintain windows in the place I put them before the screen went to sleep?
