Comment # 134 on bug 1112824 from simon izor

I'm really confused why were are assuming this is a kernel issue?  What is
GNOME doing with the kernel that could cause this?

I just encountered two other users in a Discord server that I frequent that
have this same exact issue (GNOME is extremely sluggish and they have Intel
CPUs), but only with GNOME, and only on Tumbleweed.  All other DEs work fine. 
All other distros with GNOME 3.30 work fine.  

There's gotta be some patch we apply to GNOME or *something* along those lines
causing this... it seems extremely unlikely that it would be the kernel as
these users have no issue using KDE Plasma or Xfce on the latest Tumbleweed
snapshot (20190126).  GNOME runs much slower for both of them on Tumbleweed
than on Arch or Fedora, but only GNOME.  As I said above, what would could be
going with the kernel that would *only* affect GNOME?
