Greetings,
Is there any way to disable DPI scaling in QT 6?
Thank you,

Yes, it's possible, using environment variables.
Not sure about other platforms, but on Windows, setting following environment variables before launching your program works fine:
set QT_ENABLE_HIGHDPI_SCALING=0 set QT_FONT_DPI=96The first variable disables DPI scaling: i.e. widgets and
QPainterwill not do any scaling - 1 px line will be one physical pixel wide on the screen.The second variable disables scaling of fonts.

@martin_ky That's what I've been doing for the app I'm developing, can this cause any problems for non resizable apps?
