      Description

      Hi guys,

      Customer use Repeator to create 5000 items to show different color , meanwhile items will refresh different color in every 25 ms.
      When ran it on Ubuntu the cpu usage is over 100% , you check the snapshot called ubuntu usage.png.
      When ran it on Windows the cpu usage seemed normal , the snapshot called windows usage.png

      they use Integrated video card named intel HD 630.
      I think intel graphic driver is not good on ubuntu maybe but I don't have enough technology to update it.

      I attached their test demo. Could you give me some addvices?
