Comment # 3 on bug 1178474 from Thomas Zimmermann

Quoting myself from the email to opensuse-factory

> In regular intervals, gvim stops updating the screen and freezes. I have to flip to separate workspace, which un-freezes gvim. All my key strokes were processes, as I can see the characters after unfreezing. Also, sometimes the overview screen doesn't update the small workspace previews.

> I suspect this is a bug in GNOME shell 3.38, which maybe doesn't compose the updated windows correctly.

I suspected a GNOME issue, although the bug report points in a different
direction.
