Why letters with accents (é, à, ...) are bonded to each next letter ?

Hi,
I use Opera browser (in French) and on every website, the letters with accents (é, à, ...) are bonded to each next letter.
This problem appeared after I went from Windows 7 to Windows 10.
I have the latest version of Opera. This kind of problem doesn't appear on Gmail.

Could you help me ?
Thanks
