Memory leak with 23.1.1_2?

[PotatoCarl]

Hi
Right after the last update I see that the memory consuption is very high on my system (>>90%).
Most of it is made up by "inactive processes". They form like a stepwise ladder during the day and are killed somewhere late in the evening.
The strange thing is, that if I look at a long term overview, this only.
It started around Jan 20 this year right after an update.
Since then it seems to get worse.
