[Bug] Context menus and floating toolbars in WPS Office are consistently blurry on popup until hovered over

[Naerelyth]

Environment

• OS: Fedora Linux 44
• Desktop Environment: GNOME 50.3 (Wayland)
• Extension Version: 25
• Affected Application: WPS Office

Description

After enabling the rounded-window-corners extension, popups in WPS Office (such as the text selection floating toolbar and right-click context menus) appear blurry every time they pop up.
Every single newly spawned popup initially renders blurry, and consistently requires hovering the mouse cursor over it to restore normal clarity.

Steps to Reproduce

1. Enable the rounded-window-corners extension.
2. Open WPS Office and open/create any document.
3. Select some text to trigger the floating selection toolbar, or right-click to open a context menu.
4. Observe that the popup/menu appears blurry initially.
5. Move the mouse cursor onto the popup/menu and observe that it instantly sharpens back to normal.

Expected Behavior

Context menus and floating toolbars should render sharply and clearly when opened, without initial blurring.

Actual Behavior

Context menus and floating toolbars render blurred initially and only unblur after hovering over them with the mouse.
