Cursor jumps randomly while typing

I have a 2017 (April) MacBook Pro Touch Bar system - 15", 16 GB, 1 TB SSD. When I type, randomly, the cursor will end up in some other place. This happens in all applications where text is to be keyed in (Word, Excel, even while typing this message). Sometimes the cursor just jumps and I’ll be typing in some other sentence. Sometimes it highlights entire areas of text, and I’ll type over those and have to undo if I catch it in time.

This is really frustrating and has reduced my typing speed by 70%. I never had this problem when I was using the previous version of MacBook Pro. I haven’t seen anything online about this issue, but everyone I know who has this model complains about the same problem. I need a proper solution to this problem. I have seen the same problem being reported by another user on 10th March but have not seen any reply from Apple.

Will Apple own up to this problem and give a solution to this problem? I have invested a lot of money and faith in Apple. Is there anyone who faced similar problem and solved it? If so, please help.
