Mouse cursor issue with PyQt 5.10

Description

What steps will reproduce the problem?

1. Push Ctrl key on keyboard
2. Put mouse cursor over any variable: mouse cursor changes from “text select” to “link select”
3. Release Ctrl key on keyboard

What is the expected output? What do you see instead?

The mouse cursor should change back to “text select” after releasing the Ctrl key but doesn’t ! Same problem when saving file : “text select” cursor goes to “busy” pointer but doesn’t go back to “text select” when the saving action is finished.

Please provide any additional information below

I have to get the mouse cursor out of the editor to get back the normal “text select” cursor.

This has to be an issue with PyQt 5.10 for sure, so we’re going to pin pyqt5 to 5.9.2 in our wheels. There has been several reports that things are failing strangely with 5.10.

For now, please downgrade to 5.9.2 manually.
