Please remove backdrop-filter: blur(25px); it is heavily cpu cost

[ILG2021]

tweb has some flaws, first, it build on typescript, but no react or vue, which can has better performance and faster development. Second, tweb contains some useless css to reduce performance more. When I use tweb to call a group, the cpu will go to 10%, so terrible. When I remove backdrop-filter: blur(25px); it can be 3% - 4%.
