I have upgraded my plugin to JUCE 6 and noticed the following. The drag and drop behavior when within FL studio has changed (or is broken?).
FileDragAndDropTarget::isInterestedInFileDrag is not called anymore when I drag from the FL Studio browser to the plugin component. Interestingly drag and drop within the plugin works fine and also in the standlone version there does not seem to be an issue when e.g. dragging / dropping files from the Windows explorer.
Unfortuantely debugging did not bring any further insights. The feature is quite important for my plugin. This is definitely a JUCE regression as I can test old and new behavior here right in the same session. Also switching to
DragAndDropTarget::isInterestedInDragSource did not help.
Can you give me a hint where to look at?
Edit: it is not only in FL studio. It’s happening in all DAWs (e.g. FLS, Ableton, Studio One) when using the vst2 wrapper and setting the Win 10 scaling to != 100% (see below). Sorry if I bother - but it is a showstopper for me.
