Answer to "Cursor jumping randomly when typing"I also had this problem, but a found a cheap solution. I cut out a piece of thin cardstock to fit inside the rounded-corner rectangular space of the trackpad. Then I cut out a little area in the bottom center where I could use the trackpad. It cover the upper corners of the trackpad, where my thumbs rest. I attached the cardstock with Scotch 109 Removable Poster Tape. I also turned off “tap-to-click”. This has solved my problem. If I should need to use the full area of the trackpad for an art project, the Poster tape comes off easily. I bought this 2020 MBP 13” (Intel) at the end of June 2020. It had the problem from day one. But this little piece of cardboard has solved it.
