I have 2 issues. 1. Since the newest update the program takes an extra long time to load when opening, and 2. the whole body of text turns invisible while writing, frequently and repeatedly. It's very disruptive and frustrating, as there is no sure way to get the text to become visible again. It does return to visibility after either typing, or using the space bar a number of times, but it just turns invisible nearly right away if not right away again. It's not unusable, but it is very unpleasant to use.
