<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">QScreen, through EDID reports bogus values for physicalDotsPerInch*().<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
This leads to oversized icons on monitors with bogus edid information.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch changes the ratio underlying to the icon sizing for displays<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
with a DPI > 96 * 1.5 to use the ratio between the font as rendered (its<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
effective pixelSize, essentially) to scale the icon sizes up.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">As we rely on proper font metrics throughout already, this should bring<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
sizing in line with the font, which is something that makes sense as it<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
means we're sharing the underlying mechanism (font metrics) for sizing<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
in different areas.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The downside of this patch is that we're essentially working around an<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
issue that should be fixed in the hardware, the monitor's edid.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
Unrealistic.</p>

could you run this patch for a bit and check if it works for you, too?</p>
