Weird screen on startup/installation with lit mode on, basic blank project in UE-5

I installed UE 5.0.3 on my desktop with ubuntu 20.04 yesterday. However when I open basic blank project with just two chairs it shows weird noisy screen when any of lightning mode is on(lit,lightning only, detailed lightning). Below are screenshots

  1. Lit mode
  2. unlit mode

My configurations of desktop are
i7-11700k, 8 core-16 threads, 16GB ram, No external GPU only integrated UHD 620 GPU. following are screenshot of graphic drivers and system info.


My fundamental question is, is it a driver issue or the PC config needs an upgrade ? I have other 3d software like blender that works fine so I doubt PC upgrade is required for startup kit to show ?
