[Interest] QML: non scaled image strange issue under Linux

[Alexander Dyagilev]

Hello,

I'm generating image (QR code) using QML image provider. Show it using 
Image control using actual size (i.e. width height are not specified, 
and I also set fill mode to Pad).

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.
