since installing Catalina, my mouse movement is erratic
Since installing Catalina, my mouse's movements are erratic and jumpy -- anyone else?
iMac 27", macOS 10.15
Several times a day, my mouse becomes sluggish for a few second. I tried several mouse pads, no effect, the hard wood of my desk made an alternative with the same random sluggish periods. The mouse is about 70cm = 28inch or so from the laptop...
By the way the 2 'skis' that makes the support of the mouse aren't perfectly parallel... and the mouse is wobbly. Tested on a super flat surface. Very disappointed.
