      I noticed that when you query for mouse cursor position while dragging using QCursor.pos() the cursor's position is not updated properly. I attached a test project to reproduce the issue and a video recording of the tests I ran. For comparison, I tested the same code in XWayland and it works as I expected, i.e. the position is properly updated.

      I initially created this bug report in the PySide project but was told it could be a QT core bug. Here is my original ticket https://bugreports.qt.io/browse/PYSIDE-2651

      Unfortunately, I haven't done any C++ coding for a very long while, so I cannot provide a working C++ example, but I hope that the one written in Python could be enough to reproduce the bug.

      Thank you!
