Google-chrome – Chrome zooms in when scrolling up and out when scrolling down

The following worked for me:

1. Close all Chrome windows

2. Edit the Preferences file in your Google Chrome profile.

   On Linux this is ~/.config/google-chrome/Default/Preferences; on Windows it will be in C:\Users\Username\AppData\Local\Google\Chrome\User Data\Default (or possibly C:\Users\Administrator\AppData\Roaming\Google\Chrome\User Data\Default))

3. Locate the setting "per_host_zoom_levels"

4. Remove the line that starts with "devtools". This was set to -1 in my profile (my inspector was zoomed out by default).

Just as a confirmation, do other video broadcast websites have the same problem?

If it only happens to YouTube, you could refer to the following steps:

1. Delete all your cookies and cached images from chrome for all time.
2. Sign out of your Google account and open YouTube.
3. Open YouTube and click settings in the top right and sign into your account from there. (it will look really weird to do, not like the usual login for your account).
4. Once this is done close the tab you used to login to YouTube.
5. Open a new tab and open YouTube again (either through favourites or typing it in).
6. Sign into your account via the button in the top right corner and the issue should be fixed.

If it is common, reinstall the graphics drivers and try with a shorter HDMI cable.

Hope these are helpful.
