Dark mode unreadable

[dlejay]

The following

is what I get after QGIS is opened in light mode during the day and then dark mode was triggered in the evening.
Launching QGIS while already in dark mode works fine.

This is the contrast I always obtain in dark mode in some parts of QGIS :

macOS 13.1
QGIS 3.30.2

>/Applications/QGIS*.app/Contents/MacOS/QGIS
Warning: Populating font family aliases took 104 ms. Replace uses of missing font family "FreeSans" with one that exists to avoid this cost.

Light mode has the same problem when coming from dark mode, even worse :

It is possible to better specify the combination used between 'Style' and 'UI theme', so that a comparison can be made.

QGIS version 3.30.2-'s-Hertogenbosch

You are stop on ! I was using the “out of the box” Fusion/default.
If I use machintosh/default instead, light → dark mode switch works as expected.
