Issues with Keras printing progress in Jupyter

I wasn’t able to find a solution to this, but when I run in a Jupyter notebook in Chrome on Windows, it starts printing out lots of unicode square characters and the whole browser tab freezes. Notice the horizontal scrollbar

It gets unstuck only after the whole fit() function returns and at that point it prints ouf all the text at once, again notice the horizontal scrollbar.

I didn’t have this issue on Linux though. Anyone else ran into this? Or thoughts on fixing it?
