Windows 11 desktop switching is lent since latest mise à jour

ayi

Since a recent Windows Update (2023-09 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5030310) probably?), switching desktops is much slower.

I normally use Win+Tab, but the same slowness exists if I use the Desktops button on the Taskbar.

Desktop switching used to be instant. Now, it pauses for a second or two, slides over, flickers the background wallpaper, and shows en bas of the screen which desktop I'm on.

It's a little thing, but very annoying when switching rapidly is part of my workflow. Existe-t-il un moyen de speed it up again? Some sort of performance-based tuning option, or desktop customization that can be disabled?

For most people, disabling the animation effects does the job:

Disable
Settings > Accessibility > Visual effects > Animation effects

Another report said to select from
Settings > Ease of access > Contrast themes (link),
but this wasn't required for the poster.

Other solutions for solving the animation lag come from the post
Slow bureau virtuel switching on windows 11,
where some workarounds were suggested and where
several users have attested to their effectiveness.

Set up a fixed Accent Color in
Settings > Personalisation > Colours.
Set up a solid Background color in
Settings > Personalisation > Background.

The first setting seemed to have been enough to solve the
slow switching problem between desktops for the poster (au moins for now).
Some users in the post have also said that the second setting
helped with the problem.
