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):

  • @Gantendo thanks, I don't think it's screen flickering. Just white screen displayed waiting for the window to load. – Franck Dernoncourt Jun 30 '22 at 16:06
  • @Gantendo In the demo, I minimized and restored the window a few times: when restoring the window, a white screen sometimes appears. – Franck Dernoncourt Jun 30 '22 at 16:09
  • Have you tried disabling some of the window animation effects? https://www.pcworld.com/article/423950/how-to-disable-window-animations-in-windows-10.html – DrMoishe Pippik Jun 30 '22 at 22:56
  • @DrMoishePippik thanks, yes all animations are disabled. – Franck Dernoncourt Jun 30 '22 at 23:38
  • **I wasn't able to reproduce this on my machine.** What is the resolution settings of the display? I obviously use Dark Mode – Ramhound Jul 01 '22 at 00:23
  • @Ramhound thanks, added to the question. – Franck Dernoncourt Jul 01 '22 at 01:59
  • Did you think about achieving dark mode from white mode using NegativeScreen tool? It is not suitable for entertainment, but for productivity, it is much more efficient than dark mode created by apps devs due to its flexibility. – miroxlav Jul 01 '22 at 02:29
  • @miroxlav thanks, had a few issues with it https://superuser.com/q/1553920/116475 ; https://superuser.com/q/1553010/116475 but indeed I could try – Franck Dernoncourt Jul 01 '22 at 02:37
  • @FranckDernoncourt – I see. Both linked issues now appear to be with quite an old software. Since the tool is just calling Windows Magnifier API, it is possible that it stands and falls upon it. My only issue was collision with Lenovo Vantage app, namely its enabled red filter, since it does similar trick using the same API :) I am using white mode for all apps when there is a bright day and various dark modes in the evening. I mapped it to easily reachable extra key on my keyboard (calculator) and also to Win+Left Click what is convenient when doing only mouse work :) AutoHotKey is the mapper – miroxlav Jul 01 '22 at 06:18
