Everything is very difficult, as I wrote above, the gnome is very dependent on
how well the processor works in the operating system, any error in the kernel
can affect its operation, which in turn can lead to different regressions, so
the possibility of such exclusion was it is impossible, for example, by
disabling the spectre protection, it started to work better, patches were
applied to the kernel, not the gnome, there were such conclusions from here,
currently disabling patches does not change anything at all, and he again
started to lag after the latest updates.

So GNOM works, need to check these packages, I don���t have enough skills to
check it

I tried plasma 5, it also lags me, not like a gnome, but it���s still noticeable
