This sounds similar to bug 1883456... Please:
1. Try opening the 'Extensions' app and disable 'Ubuntu AppIndicators'.
Does that fix it?
2. Run 'top' and tell us if any process is using high CPU.
3. Run the following commands after you have experienced the issue:
journalctl -b0 > journal.txt
gsettings list-recursively org.gnome.shell > settings.txt
and attach the resulting text files here.

Title:
Random stuttering while in game
Status in gnome-shell package in Ubuntu:
Incomplete
Bug description:
Updated kernel to 5.7.12 and updated nvidia driver to 450 yesterday
but only experiencing this today.
Random stuttering while playing minecraft, no clue what's causing it
but I checked system monitor and it shows random spikes of a cpu
thread to 100% and some spikes staying at 100% for a prolonged period.
It may be related to me updating my video driver that is not
recommended so I will see if switching down will resolve the issue. I
never had this issue on driver 440.
