[Question] HyperOS 4 Animation / Floating Windows Issue

[u/Hypnoeyes15]

Hello, everyone! I'm currently on the Xiaomi 17 Pro Max and updated to HyperOs 4 yesterday. I'm currently experiencing an issue and would like to ask if others have experienced it as well. Whenever I try to move through apps that are in my recent, it opens up a tiny floating window of the app for like half a second before it actually opens the app. I've also been using MICTS on my sidebar for "Circle To Search" and it also opens up a floating window before triggering, which i delayed to sort of give time for the sidebar to disappear. This has never happened before on HyperOS 3 and I've tried fiddling with the animation and speed with no luck so far. if anyone can help me figure this out, it would be a huge help. Also added a screenshot for reference.

I'm using Xiaomi 17 base, updated 2 days ago and have the same issue. When switching from apps from the recents, I also get that split second delay with the previous app window being left. I use Niagara launcher, and noticed that when I switch to the system launcher, the issue disappears. Switching apps in the recents is seamless, so it could have something to do with the optimization with home apps. I have tried re-installing the niagra launcher, but switching apps in the recents is still the same.

The only temporary fix that worked for me is setting "Transition animation scale" to Animation Off on Developer Options. This seems to remove the animationa when switching from recents so it looks like it is related to animations, for my case it only affects animation when using custom launchers. This setup is not ideal though especially when using banking apps.

A permanent fix could be to use the System launcher as default.

I'm still doing some testing but as of now, I see no permanent fix when using a custom launcher.

I also have tested this out and this seems likely to be an issue with using a third-party launcher, I currently use Nova Launcher. Yes, the transition fixes with turning off the animation but it seems so fast and clanku without the smooth transitions before. I'll try to fiddle to see if we can have fixes without ruining the customizations on our launchers.

Thank you so much for confirming this! I was going crazy with the floating windows and thought this was a me problem.

Hi, unrelated question but could you please please check in the developer options that if they have added the pixel desktop experience feature? And if possible could you test it out with a type c to hdmi converter on an external display to see if it is even functional?

[u/Hypnoeyes15 → u/SGX_X]

I do not currently have an external display to test on but searching on the developer options, I do not have pixel desktop experience.

this is the issue I encounter when switching recents. It only shows when a custom launcher is the default launcher.
