Workitems for HiDPI

As of LibreOffice 4.2.3, Windows and Linux have good HiDPI support, although bitmaps are scaled. Here's a writeup of the initial work. Note: simple scaling is generally best to make icons not blurry

OS / HiDPI detection issues

Gnome: Since version 3.10, Gnome auto-detects screen resolution and sets a 192 DPI value on HiDPI monitors. You can verify this by running "xrdb -query". Therefore, LibreOffice looks good out of the box.

KDE: In 4.x system settings, under Application Appearance - Fonts, you can set the "Force fonts DPI" to 192. When this is set, the LibreOffice HiDPI mode kicks in.

Xfce: It is possible to manually set the DPI to 192 as well.

Unity: System settings → Displays and using the slider "Scale for menu and title bars", set the value to 2. ("xrdb -query" returns 192 dpi after setting the scale factor 2, and the scale factor may be 2 by default for HIDPI screens in the future.)

Mac: Apple does auto-doubling until you turn off compatibility mode which causes some small side effects (tdf#51734, tdf#51735) Norbert is looking into it but is still in the investigation phase.

Status

A first round of fixes was released in 4.2.3, and more have gone into subsequent releases: https://cgit.freedesktop.org/libreoffice/core/log/?qt=grep&q=hidpi

Remaining

• Drawing object properties line style preview too thin
• The circles which denote the left edge of a toolbar are hard to see.
• The form navigator toolbar record selector hard-codes size

General UI

Remaining

• splash screen is too small (possible Hard Hack, see splashx.c)

Non-HiDPI specific but more noticeable

• Format - Paragraph, etc. border default of .05 pt too small
