Also in my case it was the bug 31695062 . (The allocation reason was “task parameter array”)
By the way, the bug seems to be fixed in 19.10.0.0.210119 (Jan 2021)<https://support.oracle.com/epmos/faces/DocumentDisplay?parent=DOCUMENT&sourceId=31695062.8&id=245840.1#FIXED_19.10.0.0.DBRU:210119> .

Subject: Re: PGA on higher version
Pap,
I have also been confronted with an increase in PGA consumption recently because of MMON_SLAVE not freeing up its used PGA memory. There is a MOS note which explains this issue
High PGA Consumption By Mmon Slaves In The Server (Doc ID 2700130.1)
I have also disabled the tunning advisor and the ADDM generation because I have observed a PGA leak when the ADDM advisor is launched as well.
Bug 31695062 - PGA Leak in ADDM Advisor Framework (Doc ID 31695062.8)
This is why for almost all 19c applications I am working on, I tend to disable both the tuning advisor and the space advisor
Best regards
Mohamed
