@broulik consider this case:
The tray icons' size is defined by default in
`org.kde.plasma.private.systemtray/contents/config/main.xml` to `smallMedium`,
which means 22 pixels on a 96-dpi screen. On a 192-dpi screen, the icons' real
size is 44 pixels.
Now, in `org.kde.plasma.private.systemtray/contents/ui/main.qml` there is
this line:
units.roundToIconSize(Math.min(Math.min(width, height),
units.iconSizes[iconSizes[plasmoid.configuration.iconSize]]))
The `height` property is the height of the panel (assuming the panel is
horizontal). On my hidpi screen the default panel height is around 72 pixels
(`32 px * 2`).
So the above line evaluates to:
`units.roundToIconSize(Math.min(72, units.iconSizes.smallMedium))`
`units.roundToIconSize(Math.min(72, 44))`
`units.roundToIconSize(44)`
and that gets rounded to `medium` size, which is incorrect, because we want a
`smallMedium` size multiplied by two (`32 px != 22 px * 2`).
So, on a hidpi screen the `roundToIconSize` function returns a wrong size,
and additionally it (wrongly) does not multiply the size by the icon dpi
scaling factor (e.g. `2.0`).
