<p>Exactly that is not the case.</p>
<p>Let me give you an example for broken font size: Screen "DP-0" has Scale 1 and "DP-1" has scale 1. You set "Xft.dpi: 96". The result is 96 dpi font on DP-0 and 48 dpi font on DP-1.<br />
This can only happen if Qt scales the font DPI depending on the QT_SCREEN_SCALE_FACTORS values.</p>
