Slow intel Arc GPU and missing 60Hz on X11

Hello, %username%!

I have two annoying issues on my laptop (Lenovo thinkpad x1 carbon Intel Core Ultra 7 155H).
1) On Wayland 4K videos are sometime laggy and shuttering. If I close chromium and Jetbrains IDE, the video works fine (or almost always fine).
direct rendering is enabled. Core profile is performance.

MESA: warning: Support for this platform is experimental with Xe KMD, bug reports may be ignored.
display: :1  screen: 0
direct rendering: Yes
Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Intel (0x8086)
    Device: Mesa Intel(R) Arc(tm) Graphics (MTL) (0x7d55)
    Version: 24.3.2
    Accelerated: yes
    Video memory: 15767MB
    Unified memory: yes
    Preferred profile: core (0x1)
    Max core profile version: 4.6
    Max compat profile version: 4.6
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.2
OpenGL vendor string: Intel
OpenGL renderer string: Mesa Intel(R) Arc(tm) Graphics (MTL)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 24.3.2-arch1.1
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

OpenGL version string: 4.6 (Compatibility Profile) Mesa 24.3.2-arch1.1
OpenGL shading language version string: 4.60
OpenGL context flags: (none)
OpenGL profile mask: compatibility profile

OpenGL ES profile version string: OpenGL ES 3.2 Mesa 24.3.2-arch1.1
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

2) If I use X11 instead of Wayland (Plasma) I can't choose 60Hz on external 4k monitor (but I can choose if I use Wayland)
>> Rate 60 Hz not available for this size
