libQGLViewer-2.9.1

niko-zvt commented 1 year ago

@nihenniuma I ran into the same problem when building on Apple M2 Pro (clang x64, macosx13.3, qt 5.9.9). The explicit screen selection helped me. This may not work for multi-screen systems. You will need to select a specific screen.

QScreen *screen = QGuiApplication::primaryScreen();

For example:

camera->setDevicePixelRatio(screen->devicePixelRatio());

@GillesDebunne it seems that the screen() function is not available in a UNIX-environment. Is explicit screen selection enough, as I presented above?
