devicePixelRatio = 1 (wrong) for macbook retina display. Images and text blurred.
-
Hi I've been working on an application in Qt for a few months now and out of nowhere it started rendering fonts and icons blurry. I checked my logs where I spit out the devicePixelRatio of the main window's screen and instead of being 2 (which it was before - I am developing on a retina macbook) it is now 1 (same machine).
my Info.plist file has:
<key>NSPrincipalClass</key>
<string>NSApplication</string>
<key>NSHighResolutionCapable</key>
<string>True</string>as well as in main.cpp I am setting my application to use highdpi:
a.setAttribute(Qt::AA_UseHighDpiPixmaps);
Any help very much appreciated!
Thanks,
k

Hi,
Which version of Qt are you using ? On which version of OS X ?

Might it be due to this known issue? https://bugreports.qt.io/browse/QTBUG-37095
