Public bug reported:

I've noticed lately that the performance of the UI in Gnome 3.36.2 seems
to decay with uptime.

The most obvious manifestation is that over time, window animations have
a delay and feel "sticky". Applications themselves seem unaffected. When
I tell gnome to switch workspaces, there's about a half second to full
second delay before the animation happens. This also applies to things
like pressing the meta key to show all my windows or pressing alt-tab.
Each one appears to share the same delay.

I'm running a fairly unremarkable desktop setup using vanilla gnome on
Ubuntu 20.04.

My research on this issue seems to indicate that there were memory leak
issues in 18.xx versions of the OS, but that those were supposedly
fixed. The only thing I can conclude at this point is that a new issue
has emerged, there was a regression, or the original fix didn't work.

The animation delay is sapping productivity to the point that I
eventually have to reboot my system. The gnome-shell process definitely
leaks over time as it starts around ~300mb and if left for a day will
sit at ~600mb or more.

Regarding my overall hardware and nominal state of my system, I'm
experiencing this issue even as I'm creating this question. I'm running
the stock/vanilla gnome desktop, not the ubuntu customized one.

My system has 32gb of RAM, only 6gb of which are in use currently. My
CPU usage fluctuates across 12 vcores up to 20% max. I have an RTX 2060
for my GPU.

At least as best as I can tell, I see no issue with the amount of
resources gnome-shell is getting right now. 😉

There also appear to be other accounts of this same issue building up
since the release of 20.04. It's clear that this is a widespread issue:

I would treat this with some urgency as for regular users this bug
renders the OS completely unusable.
