This was the case in Safe mode, but not with a new account until I activated Karabiner - so it seems clearly to be the cause; I would barely have cared except that for a while the Dock took about ten secs. appear and the mouse cursor wouldn't appear unless clicked on. The hiding occurs with Chrome and Safari but not on the Desktop.
iMac is 16,2 with Intel Iris Pro Graphics 6200 1536 MB and a Samsung SSD.
