[Feature request] HiDPI scaling images

[eddiezato]

I use HiDPI scaling 150% on my monitor. It also affects QV. If you zoom in to 100%, it will actually display at 150%.

I have the workaround for this:

QApplication::setAttribute(Qt::AA_UseHighDpiPixmaps);
QApplication::setHighDpiScaleFactorRoundingPolicy(Qt::HighDpiScaleFactorRoundingPolicy::Floor);

But it also makes the interface small, so I think it would be nice to be able to disable HiDPI scaling only for images, but still scale the interface.

I'm in the same situation (my 4K display is set to 1.5x, so it's virtually 2560x1440).

As you point out, I noticed that on that display it was showing exactly 1.5 times its native size.
However, other parts of the app will be displayed at 1.5x magnification, which is correct.

Note: In Qt5, this magnification was ignored, making the app difficult to use in high-resolution environments.

I don't think it's a high priority, but it's been fixed.
