On my multi-monitor setup, the window will frequently creep from anywhere on the left window to the right edge of it, jump across to the right monitor, then creep to the right edge of that monitor. It will then move up and down until it stops about 70% of the way up the right window edge, no matter where it began.

Attempting to click on and drag the window back where it originally was results in it jumping back and forth between the mouse and where it 'wants to be'.

Once it settles, I can occasionally pull the window back to the original position and have it stay there. Other times, it will continue to jump back where it 'wants to be'.

Doesn't happen all the time. maybe 70% of the time, within 20 minutes of the start of a call.
