update:
Just went to an Apple Store today and this seems to be a common issue with the 14-inch model.
Out of the two 14-inch demo's that I tried, both of them had this issue. I also tried a 16-inch but didn't have a problem on that one.
Given the fact that this is a long-existed issue from last year's 13-inch M1 MacBook Pro and Apple still hasn't fixed it till now, I don't expect this defect to go away any time soon.
