OK, I can live with scale logic always active. But why is it so blurred when scale is 100%... For me, it's definitely a bug... But it seems I'm too lazy to file one yet bug report...

Windows and macOS - works fine.

Linux (Ubuntu) - it's shown blurred. If I set smooth property to false -
it's shown as expected.

Is it a bug? In docs it's stated that smooth has no effect if image is
not scaled.

Qt 5.12.12.
Just drawing a line from point A to point B without looking at the code, the Ubuntu/Linux logic path appears to always execute the scale logic even when the scale factor is 100%. I suggest you file a bug which will probably be reclassified as a "performance enhancement request" to skip image scaling when the scale factor is 100%
