[Interest] Conflicts with Qt Qml Engine? - Are there any DaVinci Resolve team members around?

[Fabian Kosmale]

Hi Nuno,

in general, the host and plugin should not influence each other. There 
is however one exception: Import paths specified via environment 
variables (like QML2_IMPORT_PATH) might still affect the plugin.

Qt 6.10 allows setting the Qt::AA_PluginApplication attribute to avoid 
that issue 
(https://codereview.qt-project.org/c/qt/qtdeclarative/+/627695), and if 
you follow the referenced bug, you actually find a mention of DaVinci 
Resolve as a host where this was necessary.

I assume that using 6.10 beta is not an option for you project, but you 
should be able to get the same behaviour by explicitly setting 
QQmlEngine::setImportPathList to the subset of import paths you care 
about – notably those in the Qt resource system, as that should be 
completely independent from the host.

Lastly, if even that does not help, collecting more information about 
import process (via 
https://doc.qt.io/qt-6/qtquick-debugging.html#debugging-module-imports) 
would help to narrow down the issue further.

Kind regards,
Fabian
