            Bug ID: 108526
           Summary: Calc not Win10 DPI aware, display elements missing on
                    4K screen
           Product: LibreOffice
           Version: 5.3.3.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Calc
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: craig at arno.com

First, there is a solution, read on...

I am running a Surfacebook 3000x2000 resolution with an external 4K monitor
4096x2160 resolution.

When I open calc every third horizontal cell separation line is missing from
the display. At first I thought this might be a feature, but later realized
it's a bug.

The "solution" is to set Windows LibreOffice application properties to
"Override high DPI scaling behavior"  "Scaling performed by: System".  With
this property set all calc row lines reappear.

This new Windows 10 "feature" is messing up many more mature Windows products
on high DPI displays.  I'm finding many applications have a file like
"scalc.exe.manifest" which contain XML like:

  <asmv3:application>
    <asmv3:windowsSettings
xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
      <dpiAware>false</dpiAware>
    </asmv3:windowsSettings>
  </asmv3:application>

The critical part is "<dpiAware>false</dpiAware>" to allow an application to
display as it has on prior MS Windows products.

I adjusted this setting on the LibreOffice launcher and now everything looks as
it has on earlier versions, and matches appearance under Linux.
