Should I disable GPU hardware acceleration for Microsoft teams?

There should be no need to disable Team's GPU hardware acceleration unless you are having graphical glitches with the app.

Run Disk Utility First Aid on the hidden Container. To see the hidden Container within Disk Utility you need to click on "View" and select "Show All Devices". Even if First Aid reports everything as "Ok" click on "Show Details" and look to see if there are any unfixed errors or warnings listed which will require you to completely erase the whole physical SSD and restore from a backup or clone.

To look for software issues run EtreCheck and post the report here using the "Additional Text" icon which looks like a piece of paper.
