           Summary: LibreOffice apps become blurry when moved to a
                    different DPI monitor on Windows
           Product: LibreOffice
           Version: 7.2.2.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: UI
          Assignee: [email protected]
          Reporter: [email protected]

Description:
LibreOffice is not properly handling the DPI change when being moved between
HiDPI and LowDPI monitors.  It always looks good on my primary display (as set
in Windows), but on my secondary it looks fuzzy or pixelated.  Changing my
primary monitor and restarting LibreOffice results in it looking good on
whichever one is primary and bad on the other.

Changing the Windows compatibility settings on LibreOffice to override scaling
behavior to "application" results in LibreOffice always looking sharp, but not
scaling to the correct DPI.

I see this problem with versions 7.1.7, 7.2.2, and 7.3.0.0 alpha 1.

Steps to Reproduce:
1. On a computer with dual monitors, set one to 100% scaling and the other to
125% scaling.
2. Open any LibreOffice program, such as Calc.
3. Move the program to the secondary monitor.

Actual Results:
Every single part of the UI is blurry, including all text, icons (svg), menus,
and dialogs.  The only part that's not blurry is the title bar drawn by Windows
itself.

Expected Results:
I expect the program adjust its scaling when moved to a different DPI monitor
to keep everything sharp.


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes
