Hi,
Thanks for your post in Microsoft Community.
I understand you're having issues with windows rearranging when Windows is reopened after hibernation.
This problem may be caused by the graphics Display Driver.
What graphics card are you currently using? Is it using only discrete graphics or discrete graphics + integrated graphics or only integrated graphics?
If you are using a discrete graphics card only, then you can go to the official website of your graphics card manufacturer to download the latest version of the driver for an earlier version and install it to see if it fixes the problem.
If you are using only integrated graphics or discrete graphics + integrated graphics. Then you can try pressing Win+X, select Device Manager and open it.
Find "Display Adapter" - select your integrated graphics card - Uninstall the Device
Restart Windows after uninstalling the device and wait for Windows to automatically retrieve the appropriate display driver.
Then see again if there is a problem.
Please feel free to let me know how it goes.
