Problem with numpy array viewer in PyCharm 2020.1

Question

In the recent update for PyCharm CE 2020.1, they've botched up the numpy array viewer. To be specific, I'm unable to increase the size of the viewer window, vertically. It shows just 4 rows at a time, even when there is ample space. Please see the pic below:

Is there any quick fix for this? That will greatly help me:)

Answer 1

That's a regression in 2020.1 - https://youtrack.jetbrains.com/issue/PY-41601

The fix is ready and is in testing right now, should be included in 2020.1.1 minor update.

Answer 2

I think that gray color rectangle is a scrollbar
