Fails to start on a system with hybrid graphics

Description:

Digikam fails to start after upgrading qt6 from 6.8.3 to 6.9.0.

This happens on a system with hybrid AMD graphics (integrated GPU and dedicated GPU), but it was working fine before this qt6 upgrade.

Steps to reproduce:

pacman -S digikam
Run digikam.
Splash screen appears, but force closes and main window never appears. Last message in the splash screen is "Checking ICC repository".

A core dump is created.

Mitigation

Digikam starts correctly when setting DRI_PRIME=1 environment.

Setting QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu" environment also works (thanks to this comment on BBS). This should narrow down the issue to that specific subsystem.

This is the relevant part of the console log with the mitigations enabled:

qt.multimedia.ffmpeg: Using Qt multimedia with FFmpeg version n7.1 GPL version 3 or later
kf.xmlgui: Unhandled container to remove :  Digikam::DigikamApp
kf.notifications: No event config could be found for event id "DbCleaner" under notifyrc file for app "digikam"
kf.notifications: No event config could be found for event id "ThumbsGenerator" under notifyrc file for app "digikam"
qt.qpa.wayland: Creating a popup with a parent, QWidgetWindow(0x642466a55150, name="DigikamWindow") which does not match the current topmost grabbing popup, QWidgetWindow(0x64246c0627e0, name="QMenuClassWindow") With some shell surface protocols, this is not allowed. The wayland QPA plugin is currently handling it by setting the parent to the topmost grabbing popup. Note, however, that this may cause positioning errors and popups closing unxpectedly. Please fix the transient parent of the popup.
