--- Comment #21 from Nicolas Fella <nicolas.fella at gmx.de> ---
Git commit 4fe57a690816188ab2a182a546b6fd3f34d5fabd by Nicolas Fella, on behalf
of Konstantin Ivanov.
Committed on 25/03/2025 at 20:55.
Pushed by nicolasfella into branch 'release/25.04'.

Extend using offscreen platform for thumbnail creation by using original
platform theme.

A previous commit 1fe1548a introduced offscreen platform to the thumbnailer but
also a regression where directory thumbnails were built using the default
platform theme. This results in e.g. incorrect colors being used.

To preserve the original platform theme we create an auxiliary QApplication and
then set the platform theme with QT_QPA_PLATFORMTHEME environment variable.
(cherry picked from commit e11dfd86bd075afc7ff5c5eec70bc5d2377c4168)
