It's happened quite a few times on a work laptop running Windows 10 with a 2nd screen / monitor, and it's happened to me once at home 2 weeks ago.
I did various stuff and in the past 2 weeks it hasn't happened anymore. I think this might be the one that nailed it:
Open regedit, and navigate to the following key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Avalon.Graphics
Add a new DWORD value named: DisableHWAcceleration
Set its value to 1.
Restart your PC.
* * * *
In case you don't want to disable HW Acceleration, changing resolution seems to work. Just change it to something else on the big screen / monitor, then back to your default. The problem should be fixed.
To do it a bit faster you could either use an AHK script to change resolution, or a PS script to do that.
1. AHK Script (need AutoHotkey installed or use it to compile an exe file)
#NoEnv ; Recommended for performance and compatibility with future AutoHotkey releases.
; #Warn ; Enable warnings to assist with detecting common errors.
SendMode Input ; Recommended for new scripts due to its superior speed and reliability.
SetWorkingDir %A_ScriptDir% ; Ensures a consistent starting directory.
#SingleInstance, force
detecthiddenwindows, on
; Use command prompt to open display settings
Run, %comspec% \k,,hide, cmd_pid
WinWait, ahk_pid %cmd_pid%
ControlSend, , control desk.cpl'n, ahk_pid %cmd_pid%
; Wait for display settings to open
WinWaitActive, Settings
sleep, 2000
; Send the appropriate key strokes to the settings menu to change the resolution
Send,{Tab 4}
sleep 100
Send,{Enter}
sleep 100
; Change this as needed to move to the desired display settings
Send,{Down 4}
sleep 100
Send,{Enter}
return

2. PS Script (need to right click it and select Run with PowerShell)
Function Set-ScreenResolution {
