Comment 4 for bug 1587660

These strange occurrences happen rather often, and in the latest of one of these when I logged back in again everything had gone mad, the selected window was madly flashing (going between the focused and unfocused state very quickly even though I wasn't doing anything that should cause this, in fact, most of the time I wasn't doing anything at all) and so text from half of the date and time at the top, and the Activities Overview text, when I finally managed to close the window, the flashing stopped on that side of the screen and then the window which was behind the other one grabbed another part of my screen and started having the same affect on it.

I wanted to shutdown my machine, but when I opened the pull-down menu with the shutdown button I noticed that all text had gone, it only returned, though briefly, when I went over it with my cursor.

And as this is all happening rather regularity and getting worse, my machine is becoming harder and harder to use, I'm having to restart gnome-shell all the time.
