            Bug ID: 131946
           Summary: Blurred interface on High DPI screen (100% scale)
           Product: LibreOffice
           Version: 6.4.2.2 release
          Hardware: All
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: stephane.guillou at member.fsf.org

Description:
Using Windows 10 and LO 6.4, the interface is blurry on a high DPI screen, even
with the default of 100% scale.

Steps to Reproduce:
1. Open a LibreOffice component after default install

Actual Results:
The interface is blurred, pixelated (icons, text, menus... everything, see
attachment)

Expected Results:
The interface should be neat.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Deactivating OpenGL did not help.

One way to fix that is the following:

1. Find the executable Program Files\LibreOffice\program\soffice.exe
2. Right click and open "Properties"
3. Go to "Compatibility > Change high DPI settings > High DPI scaling override"
4. Tick "Override high DPI scaling behaviour" and change the scaling option to
"System (Enhanced)" in the dropdown.

The interface then looks good after a restart of LibreOffice (see attachment).
