Outdated CEF causes backdrop-filter blur flickering in NUI #3843

Description

What happened?

When using CSS backdrop-filter: blur() inside a NUI, the blur effect flickers continuously in-game.
The UI appears to constantly repaint, causing visible instability and making modern UI blur effects unusable.

This happens consistently across servers and different UI implementations.

Expected result

backdrop-filter should render a stable blur effect without flickering or constant repainting. Modern CSS visual effects should behave similarly to standard Chromium behavior.

Reproduction steps

Create a simple NUI with:

backdrop-filter: blur(10px);

Open the UI in FiveM

Observe blur flickering and unstable rendering

Importancy

Slight inconvenience

Area(s)

FiveM

Specific version(s)

Embedded CEF: cfx-m103 (Chromium 103)

Additional information

CEF appears significantly outdated compared to current Chromium versions.
Developers cannot update or replace the embedded CEF themselves, as it is tightly integrated into FiveM.

Is there any plan to update the CEF version or address the rendering instability?
