There's a few things in particular we need to identify:
- Widgets which are now showing as pixelated. Basically just hunt
through the UI looking for things which look pixelated! This might be
icons, graphics, or even just the drawing of the widget itself. You'll
spot them immediately, as they clearly stand out. But there's a LOT of
different dialogs/tabs/widgets/pages/... in QGIS and it will take some
time to hunt through them all.
- Icons/images which look the wrong size. Eg the marker symbols shown
in the layer tree right now are incorrectly sized and will be half the
size of the actual symbol shown on the map. That's a known regression,
but there's likely others like this hiding around the place.
- Text which is the wrong size. If something has a hard-coded sizing
it's possible that we'll get fonts scaled badly, so if you spot any
text which noticably looks incorrectly sized vs other UI elements then
that's also something we need to fix.

This is EXACTLY the kind of setup we need testing on! If the display
scaling is set to 100% (in Windows, or Linux), then you'll see no
difference between the old approach vs new. The new logic only kicks
in when display scaling is present.

Things should just look perfect, regardless of whether or not display
scaling is active :)
