Comment # 45 on bug 1112824 from Dead Mozay

After several days of tests with a compiled kernel without patches, I can say
that this partially solved the problem, the application review is smooth, but
the activites still sometimes slows down, just when I launch the application
from Dash, there are also signatures sometimes, while reading Twitter yesterday
I came across several posts about The fact that the brakes appeared everywhere
when the activities was activated. perhaps this is due to patches spectre v2,
now they are just deciding what to do with them, Linus suggests that they be
removed from the code at all, he considers it unwise to use them in the kernel,
referring to the fact that it will be necessary for someone to disable the SMT
in the bios.  Corrections promise in GNOME 3.31, backports may be done, but
this is not accurate.
