Electron Version

17.0.1

What operating system are you using?

Windows

Operating System Version

Windows 11 (21H2 build 22000.493)

What arch are you using?

x64

Last Known Working Electron version

17.0.0

Expected Behavior

In 17.0.0, my frameless window would have the Windows 11 "pop in" and "fade back" animations when the app starts/exits

(I don't think the Windows Vista-looking frame that pops up matters. When I make the window wait to show until dom-ready that issue goes away, and that's how my actual application does it)

Actual Behavior

As of 17.0.1 the frameless window instantly appears/disappears on start/exit (I'm pressing Alt+F4 to close the window in both gifs)

Testcase Gist URL

Additional Information

I uploaded the files in a gist, but all I had to do to test this was download the quick-start and add frame: false to the BrowserWindow options

I have the same issue. It also doesn't play animation when I minimize the window.

Same problem on WIndows 10 x64, Electron v17.1.0

Also test with v14 v15 v16, no animations, v13 is ok, but seems Electron v14+ launch a bit faster.

On v18.1.0, the issue has been resolved for me.

It seems that #33599 fixed this.
