I use Windows 10 with dark mode on. Windows 10 often flashes white when displaying a window, e.g.:

enter image description here

In this demo, I minimized and restored the window a few times: when restoring the window, a white screen sometimes appears.

How can I prevent Windows 10 from flashing white when displaying a window?

All animations are disabled:

I use a GS76 Stealth 11UH laptop (4k monitor) running on Microsoft Windows 10 with a 1080p external monitor. The white flash occurs in whichever monitor the window appears. Settings of each monitor:

Monitor 1 (4k):

Monitor 2 (1080p):

Unfortunately, this is just the way Windows is designed and a result of the subpar implementation of dark mode.

You see, when you open a new window, Windows first draws that space with a white background as a buffer before displaying the actual content. Probably when they first designed it that way, they did not predict the necessity for something like dark mode years later.

You should only see this with win32 apps. The modern apps are designed with dark mode in mind and they don't suffer from this issue.
