[window-state] On Windows 11, sub windows open smaller and smaller and smaller, violating our set minimum window dimensions.

[abarrafo]

This does not happen on MacOS, and, was not occurring on an earlier build, so it might have been introduced in recent updates.

rust: 1.84
tauri: 2.2.2
tauri-plugins: 2.2.0

I have key bindings for ctrl + shift + f to open a global project search sub window, a new window with a parent. Every time I open it, it shrinks, and shrinks.

I have the following attributes:

            .inner_size(600.0, 400.0)
            .min_inner_size(600.0, 400.0)

The window is starting out below this minimum threshold, and gets worse. It does snap back up to the min as soon as I grab a corner to perform a resize event.

When I remove the plugin from lib.rs, the problem demonstrated below, stops.

Opening additional windows, not marked with a parent appears to be unaffected.

We have some recent changes fixing the window size setters and getters, do you mind upgrading tauri (also the dependency tao) to latest version and try again see if the bug still happens?

[abarrafo]

Not sure if its related, but I had seen some issues on linux also where child windows were opening up behind the parent, which this seems to have fixed.

In regards to Windows 11. I still am experiencing the behavior above with the windows getting smaller and smaller.

I can't reproduce this myself when trying to run this code inside this repo's API example

new WebviewWindow('child', {
  parent: getCurrentWebviewWindow(),
  decorations: false,
  width: 500,
  height: 500,
  minWidth: 300,
  minHeight: 300,
  visible: false,
})

Do you mind sharing a minimal reproducible example? (Also instead of sharing the dependencies inside package.json and Cargo.toml, the output of tauri info from tauri cli will tell us the exact version of related packages are more helpful)

Here is a simplified app:

https://github.com/bookcicle/tauri-window-testing

that demonstrates the behavior.. After some further testing, it seems to present on extended monitors. And, it turns out the behavior is different, depending on the monitor resolutions.

If my app is running on an extended monitor, that has a 1920x1080 resolution.. We see the following:

Recording.2025-03-31.135447.mp4

Strangely, if we move the window over to a 5k monitor, it has the inverse behavior, where the child window opens larger, and larger and larger.

While opening on my primary monitor (4k) there is no issues.

If I switch my primary monitor to my 1920x1080 display, then the child window opens normally there, but now starts growing on each close/open on my 4k monitor, similar to the 5k behavior

[abarrafo]

Demonstration on 4k/5k monitor when not the primary monitor.

[FabianLars]

Do you have different scaling set up on those 2 monitors?

[abarrafo]

Yes! That gets us close to the cause.

Scaling is set as follows:

FHD - 100% (shrinks when not the primary)
4k - 150% (grows/shrinks when not primary - depending on which is marked as primary)
5k - 200% (grows when not the primary)

If I set all monitors to 100% scaling, then the issue is no more...

[Legend-Master]

Hi I just made a PR trying to fix this problem at #2583, but I don't have another monitor to test right now so I asked a friend to test it (4k monitor at 200% as primary and a 1080 monitor at 100% as secondary) and he said it works fine, could you also give it a try and confirm if it fixes the problem?

[abarrafo]

Confirmed. The above resolves it. Thanks so much.
