LibreOffice doesn't support HiDPI well.

[Shih-Yuan Lee]

Ubuntu 14.04.2

Reproducible Steps:

1. Login Unity desktop environment.
2. Change the scale factor to 2 in Displays of System Settings.
3. Open any application of LibreOffice.

Expected Result:

* The icons and toolbar will be scaled up by 2.

Actual Result:

* There is no change for icons and toolbar.

Status changed to 'Confirmed' because the bug affects multiple users.

At least on GNOME/X one can control LibreOffice scaling likeso:

GDK_DPI_SCALE=0.5 libreoffice --writer

- this would reduce the vertical size of fonts to 50%

X does not support different dpi per display, so in a mixed e vironment you could decide which window goes on which display and scale accordingly

Wayland supports per-display dpi

This works for me with Ubuntu 16.04.3 and the packaged LibreOffice 5.1.6.2. Can this report be closed?

Yeah it works fine for me on 18.04 and Libreoffice 6 too.

Closing per user feedback. Thanks!
