Yup - that would be a tiny screen, as it's in mm...
xdpyinfo seems more correct with "508x317 millimeters"; not sure if this is a
guess based on the 96 DPI or on real data.
The icons are roughly scaled 3x when I tried to measure their rectangle using
gimp, so that would correspond to logicalDotsPerInch : physicalDotsPerInch.
Currently Qt5Font uses QFont::setPixelSize to set the font size. Quoting the
docs: "Using this function makes the font device dependent. Use setPointSize()
or setPointSizeF() to set the size of the font in a device independent manner."
So in theory
- setPixelSize(rFSP.mnHeight);
+ setPointSizeF(rFSP.mfExactHeight * 72.0 /
QGuiApplication::primaryScreen()->logicalDotsPerInch());
should fix your problem. Docs for QScreen::logicalDotsPerInch claim "this value
can be used to convert font point sizes to pixel sizes".
My final patch is a bit different. LO still looks ok for me, but I have no
idea, if this would work for you.
Maybe this needs adaption of Qt5Font::ImplGetGlyphBoundRect too
Can you test the patch at https://gerrit.libreoffice.org/#/c/65696/ ?
