Ever so often, in Writer, the screen display goes wonky. Text is distorted. Typically, one to three lines of so get squeezed and distorted. Sometimes, one or more lines get squeezed down to a row of dots. I’ve tried in vain to find a “refresh screen” or “refresh vies” function, but maybe I’ve just overlooked it. (The web-based help makes it MUCH, MUCH more difficult to find any useful information on the program, BTW. I’ve given up on it.)
The workaround I found by accident is to bring up the find box at the bottom of the page. Suddenly the page is displayed correctly! But this is annoying, besides being obscure.
It may be relevant that I’m normally working in very large documents, or it may not. Contents are such that I don’t want to pass on a screen shot, and it’s erratic enough that I’m not willing to take the time pretending to edit something I can pass on that way until it happens. It can be several times a day, or several days.
