PyQt5 V5.15 Blocks context menu mouse event
-
My problem is on an OSX previously developed application with a popup GUI, which was fully operational using PyQt5 V5.14.2 but stopped working from V5.15.0 onward.
This seems to be a PyQt bug which is blocking the context menu mouse signal when <setWindowModality(QtCore.Qt.ApplicationModal)>.
Right click brings up the context menu fine but selecting an item is blocked using the mouse.
Using the keyboard however to navigate and select works fine.I have no idea how to raise this as a bug in Qt or if anyone has a solution.

Hi and welcome to devnet,
Since it's an issue that looks like a regression in PyQt, you'll have to contact their author.
