Hey everyone, I've rewritten the macOS and Ubuntu UIs in Compose, and thanks to my Tao backend, they now have native windows!
You can try the web demo, but please, download the gallery on your computer!

I downloaded the demo app to my MacBook Pro M4. When I grab the lower right corner of the window with the mouse and quickly move it around, I see the box with the rounded corners on the left jumping up and down. I doubt that this is how it should look like.

<@U01ERMR974M> I have the same (or very similar) issue, but I thought this was specific to Linux/Wayland! If you are experiencing this on a MacBook Pro M4 then the fixes I am attempting with the help of Claude (<https://github.com/NucleusFramework/Nucleus/pull/445>) are definitely not addressing the root cause.

Can I ask which demo file you downloaded and ran?

Any chance of a screen recording of the drag? Even a phone video pointed at the screen. I want to see if its the same issue I am having.

Does it still happen if you resize slowly, or only when you move quickly?

Are you running with any scaling active?

I have downloaded <https://github.com/NucleusFramework/compose-macos-26-ui/releases/download/v1.0.0/macosui-sample-1.0.0-mac-arm64.dmg|macosui-sample-1.0.0-mac-arm64.dmg> from <https://github.com/NucleusFramework/compose-macos-26-ui/releases/tag/v1.0.0|github.com/NucleusFramework/compose-macos-26-ui/…/v1.0.0>
I'd say it happens always.
I have a big screen with the default (2.0) retina scaling.
Screen-recording is attached.

Thank you, that looks suspiciously similar to what I am experiencing on Linux
