--- Comment #10 from Kurt Revis <krevis at figma.com> ---
Looks like the fix came with recent ANGLE changes.

Relevant recent commits on main:
404173 "Update ANGLE to 2023-02-08"
ab998e "ANGLE Metal program memory cache is unbounded"
b37b92 "Update ANGLE to 2023-02-14"
68fbc8 "Update ANGLE to 2023-02-20"

Before 404173, the situation is very bad -- the GPU process grows in memory very quickly.
404173 was an improvement but not a full fix. It's still bad but grows more slowly.
ab998e does not appear to affect this case.
b37b92 caused memory usage to become stable.
68fbc8 does not appear to affect this case.
