I'm facing strange issue on Windows 10. Same application behaves different on same windows version - the difference is seen at title bar appearance:

Above is normal, expected (at least by me) behavior - all three buttons are in the right corner, the application logo and title in the top-left. Under certain circumstances (which I can't find and thus need your help) the same application title bar looks like this:

enter image description here

The three buttons take all the length of title bar and centered in it, title bar's height is 30 pixels longer, application logo is top-right and application title disappears at all.

The question is what windows 10 setting(if any) causes such difference for same application? Thanks in advance.

  • did you customized title & fonts?

  • I don't know, this came from user. That is exactly the question - what customization can cause such appearance ? Mar 21, 2017 at 15:02

    1)DPI scaling... ( it looks so he set 125% instead of normal 100%) 2) Custom font size (as i said earlier)

    Like @Reborn said, it's probably caused by DPI scaling or custom element sizes in the Windows Personalization section. One thing to note is, you have to log off, log back in for it to take effect completely. User sees "You must log out" message, user says "Pfft!" and closes it, and then different apps display differently in confusing ways. Have the user log out and back in. Mar 23, 2017 at 15:13

You can use this Registry tweak from winaero.com:

  1. Press Windows Key+R and in the box that pops ups type regedit.

    Note: Extreme caution is advised when using the Registry Editor.

  2. Once you are in Registry Editor go to the key:

    HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics
  3. Click on the string value named CaptionHeight and set its value using the following formula:

    -15 * The desired amount of height you want

    For example, if you want to set the bar height to 18 pixels you would change it to -15*18 = -270.

    enter image description here

  4. Sign out and then back into your account to make the change take effect.

    This does not explain why the same application is showing differently on different occasions.
