Mouse cursor fails to change after sleep in Windows 10

Question

Today I started having a frustrating problem with my mouse cursor. It appears to manifest after waking from sleep mode, but be fixed temporarily by a reboot. I haven't found any way to reproduce it consistently, but I suspect it's related to my monitors acting differently in sleep mode.

Sometimes after a long hibernation Windows doesn't detect one monitor on wake, so everything goes to my left monitor, and then back to my right (primary) monitor after it wakes up, which ends up pooling all my windows in one place. This was mostly annoying before, and hasn't caused this mouse cursor issue for a couple years but is a possible trigger since every time the cursor has messed up it's been in this scenario.

The general symptoms are:

1. Mouse cursor icon will not move to second screen. The cursor itself will move over and be able to interact with windows, but the icon is stuck on the left side of my right monitor as if it can't go over (so the cursor is effectively invisible until I go back to my primary monitor).
2. Cursor "sticks" in different icons. So if I hover over a link, it will stay a hand pointer until I mouse over something that doesn't have a hand pointer (e.g. a window resize) except...
3. The selection cursor will never appear, as in the text selection cursor that looks like an I will be rendered invisible.
4. In addition, the cursor icon gets glitchy whenever I mouse over any icon on the taskbar (but as with everything else, operates normally in every way except visually).
5. Oddly, I've noticed that Windows will detect fullscreen applications as if they're resizable from an icon perspective (that is, if I mouse over the edge of the window my pointer changes to the the resize arrows) but it will not allow me to resize the window i.e. it correctly knows it's in fullscreen.

I have a RTX 2080 graphics card with up to date drivers, reinstall hasn't fixed it. Unfortunately general troubleshooting is difficult due to the inability to reliably reproduce the behavior. Most advice I've found online just walks through to change your display settings to arrange your monitors properly, which isn't my issue.
