Description Egbert 2016-05-31 14:02:03 UTC
I have a HiDPI screen (15'' 3840x2160 -> physical DPI = 282), and I have KDE/Plasma configured to a scaling factor of 1.5 and a DPI of 168. I do not want to set it to 192 because I like to have a bit more screen estate, even though the physical DPI is (a lot) higher.

Because it's below 192, the HiDPI-mode in LibreOffice is not enabled. Even though the fonts are properly scaled according to DPI of 168, the toolbar buttons are unclickably small, probably assuming a DPI of 96 or something in that direction.

Plasma allows me to set a scaling factor to my own liking and a DPI-setting to my own liking, why is LibreOffice forcing me a specific threshold for HiDPI to kick in?

Icons should just be scaled based on actual DPI rather than switch to different icons on a specific threshold. I'd rather have not-perfectly-scaled images than unclickable (but sharp ;)) images.

It would be great if LibreOffice would respect the scaling factor I configured in Plasma.

Confirmed. We currently support only integer scaling factors.
