Spikes appear in my text

In the newest update, a bug has been added in which spikes appear in my text, ruining it completely.

Here's the link. The red circles point out the spikes.

Interesting. Share the project, in the usual manner. Someone will check it out.

Confirmed, same here.

Consider dropping back to the 16.x series. Or give 17.04 beta a go, where the issue is fixed.
