Text area completely fails to clear during redraw

[Chris West]

At some point since after the 17.10 upgrade, the main text area has been totally failing to redraw properly for me. Scrolling results in complete garbage being displayed. Selecting everything redraws the background to orange, so you can temporarily see what's going on.

Here's a short screen recording of me selecting, scrolling etc. the text to show it being complete garbage:

I'm using the nvidia binary driver, and i3. Running a compositor doesn't make any difference.

I presume the problem is in some gnome library, not in gedit itself, but the gedit bug is very.. visual.
