Ubuntu • RPI4 + Ubuntu22 + Chromium - video speed issue

Hi, I have a question about RPI4 (4G Ram) + Ubuntu 22 + Chromium. There was a problem with hardware video decoding. It is blocked by default on all APT packages for Ubuntu including Chromium. So I made some investigation and found a workaround here I succesfully unblocked the HD acceleration but the video is still slowed down.

I am at the end of my ability to fix it so I would like to find some help with it here.
Do I need to do something to fix the slow videos?

This is the result of chrome://gpu

Problems Detected
=================
* WebGPU has been disabled via blocklist or the command line.
Disabled Features: webgpu

* Accelerated video encode has been disabled, either via blocklist, about:flags or the command line.
Disabled Features: video_encode

* Disable KHR_blend_equation_advanced until cc shaders are updated:
(http://crbug.com/661715)
Applied Workarounds: disable(GL_KHR_blend_equation_advanced),
disable(GL_KHR_blend_equation_advanced_coherent)

* Expose WebGL's disjoint_timer_query extensions on platforms with site isolation:
(http://crbug.com/808744), (http://crbug.com/870491)
Applied Workarounds: enable_webgl_timer_query_extensions

* Some drivers can't recover after OUT_OF_MEM and context lost:
(http://crbug.com/893177)
Applied Workarounds: exit_on_context_lost

* Avoid waiting on a egl fence before swapping buffers and rely on implicit sync on Broadcom GPUs:
(http://crbug.com/938286)
Applied Workarounds: rely_on_implicit_sync_for_swap_buffers
