Window transparency fails on Linux

[T-baby]

I am experiencing a persistent issue where window transparency fails to render correctly on specific Linux configurations. Despite setting transparent: true in tauri.conf.json and applying background-color: transparent via CSS.

Interestingly, this issue does not occur on a different machine with an Integrated GPU and a much newer kernel (6.14).

Environment Details (Problematic Machine)

• GPU: NVIDIA RTX 3090 using proprietary drivers.
• Kernel Version: 6.8.0-100-generic.
• WebKitGTK Version: 2.50.4.
• Display Server: X11.
• Tauri Version: 2.9.5

Reference Environment (Working Machine)

• GPU: Integrated GPU (Intel).
• Kernel Version: 6.14.0-37-generic.
• WebKitGTK Version: 2.50.3.
• Display Server: X11.

ngl there's probably not much we can do, especially if an nvidia gpu is involved (webkitgtk + nvidia = problematic)
