I can not reproduce it so I am not sure what to do, also I am busy so I can't do thorough testing.

But could you provide some information. Which scale does your primary screen have?
Could you check if it does have some effect if you change primary screen?
Could you check how does less mode look and behave when dragging between screens?

My main display's scale rate is 225%, external screen 100%

Just tested your latest commit, the issue seems gone - bravo!
The only remain issue is: while the 2nd Ctrl-F to make Find dialog display on the center of Notepad++ (225%) from the external screen (100%), Find dialog increases its width considerably - but you have mentioned "the only thing missing is handling situation when goToCenter is invoked..."

So let's merge this PR and treat the dialog width increasing issue in another PR.

Thank you!
