<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">We are dealing here with real pixels. E.g. kwin asking for the icon in size 16x16, because the icon is in 16x16 on the window property. By multiplying here it picks a different icon, e.g. 32x32, which might not even exist on the window.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I think the scaling needs to be done by the user of the API.</p></pre>

I doubt that's the reason.
Also how are you checking what icons exist in the window? Arguably they should be scaled down.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The whole point of the dpr is that the client code sees <em style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">everything</em> scaled by the "magic value.
QScreen's size of the monitor is scaled, the QWindow x/y are scaled. We need our library calls to be scaled too, otherwise they're just broken.</p></pre>

make our windowing APIs match.
X (and KWin) deal with device dependent pixels, so everything needs to
be converted when communitcating geometry.
Abstraction happens in the main kwindowsystem so X and Wayland are both
supported.
