Annoying UI bug

In recent days pretty annoying UI bug appeared. There always is a tiny little think, which follows the pointer and partially hide the top-left corner of a letter, which is currently being typed. Concretely in my case it appears everywhere in the workbook.

The pop-up message says that some parsing error appeared.

I experienced the problem only in Safari 11.0.3. There seems no problem in Chrome 64.0.3282.140.

It’s a known issue, thanks for the report anyway - I’ll ask devs to pay attention to it.

The fix is finally deployed. Please write here if you encounter any other problems.
