I am having same problem at my system and I would like to add some details:

Hyprland version

Hyprland 0.51.1 built from branch at commit 71a1216 ([gha] Nix: update inputs).
Date: Mon Sep 22 20:54:03 2025
Tag: v0.51.1, commits: 6436
built against:
aquamarine 0.9.5
hyprlang 0.6.4
hyprutils 0.10.0
hyprcursor 0.1.13
hyprgraphics 0.2.0

no flags were set

Regression

Probably no

Describe the bug

As shown in the screenshot attached by @fuzunspm, floating windows created by Google Chrome (running in native Wayland mode) have an unexpected gap or margin around them.

I attempted to remove the border using a windowrule, but this was unsuccessful.

Note: This is my first Hyprland setup, so I am unsure if this is a regression or if this behavior has always existed.

Reproduction steps

1. Start a random Google Meet meeting (meet.google.com).
2. Switch to a different Chrome tab.
3. The new pop-up window (meeting preview) will appear and display the gap.
