2025 Cinnamon desktop mouse lag, 100%CPU once an hour

I have had Mint on this machine for over 3/4 years now, but either due to an update/upgrade , the machine goes to 100% about once an hour, ( showing on the desktop mini) . Problem is , I can't figure out from when. What I installed during that time , is Tauon, Bottles, some config with the Dosbox emulator. And timeshift moved to a HDD.
