no editing cursor in 3.1.0

I have Windows 10 pro.

In 3.1.0 64 bit I don’t see the editing cursor.
Is this a bug or do I have to look for a new setting?

In 3.0.4 and before I always saw it as in the picture below.

If you mean the quick play triangle that used to appear when you hover over the timeline, that indeed is no longer there as the timeline no longer is used just for quick play. You now also can click and drag to set a looping region.
