Latest PP multi monitor issues on Win10: Fullscreen capped at 1080 on main 4k monitor + waking issue

Nothing game breaking, but annoying nontheless:

I have a two monitor setup connected to a rtx3080. One is an ACER ET322QK 4k 10-bit display over displayport for my playback window and effect/source that is set to be my main display in Windows settings. My second display is a cheapo Sceptre E22" 8bit HD display in verticle orientation that I use for pancake editing two timelines simultaneously. Not sure how much of that info is relevant to my probs.

The first issue is that I mapped "F" to fullscreen the program monitor. This only works when the entire program is on my main display. When I try it with my multi-screen setup it pops out in a borderless window that isn't scalable, locked at 1080, which is about how big my program window is on the 4k screen. It means I have to use another layout to check for 4k detail.

The other issue is a bug that when my PC wakes from sleep, or monitor shutting off it resizes just the 4k window by pushing/squishing the whole thing to left, almost as if it were trying to match the verticle layout of my secondary monitor. Only takes a sec to fix, but annoying enough to come here for help.

That's all. Thanks!
