Bug ID: 150552
Summary: UI fonts rendered too small on high resolution retina
displays using macOS
Product: LibreOffice
Version: 7.5.0.0 alpha0+ Master
Hardware: All
OS: macOS (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: UI
Assignee: [email protected]
Reporter: [email protected]
Description:
UI fonts are rendered too small on laptop retina displays with native
resolution greater than 220 ppi (see screenshot 1, red boxes). Font rendering
within document area is ok, because these fonts have to be rendered at their
physical extent and independent from display resolution. For better readability
UI font rendering should be like in screenshot 2, red boxes with larger fonts
similar to font rendering on external displays.
Steps to Reproduce:
1. Open any LO application like Writer, Calc, Impress, Draw
2. Look at statusbar or sidebar
Actual Results:
UI fonts are rendered too small on displays with native resolution greater than
220 ppi (see screenshot 1, red boxes).
Expected Results:
UI fonts should be rendered larger and as large as on external displays or on
displays with native resolution less or equal than 220 ppi (see screenshot 2,
red boxese).
Reproducible: Always
User Profile Reset: No
Additional Info:
I will provide a patch resulting in screenshot 2 in short.
Reason is VCL font handling for UI fonts using integer values in points (pt).
Due to a rounding issue, fonts are rendered using a smaller height after
recalculation of font height for display resolution.
