Bug report #15357

QGIS doesn't open in HiDPI mode on OS X with retina display.

Added by Nikolay Lebedev about 7 years ago. Updated about 5 years ago.

Category:OsX UI

According to 2.16 changelog, there is an improved HiDPI support. But it's not enabled by default and I have problems enabling it.
Attached is a comparison of QGIS and Safari windows on the same retina display. QGIS still has way less pixels and looks blurry.
This overall "low-res"-ness also affects the map itself - like there is no visible difference in line widths below 0.26px (compared to image rendered with Mapnik, where it's definitely visible).
Info.plist file in QGIS App folder contains:


Changing this value to True doesn't change anything. Tested on QGIS 2.16 and master built with Homebrew.
