Bug#559955: Gnometris graphics glitch at 100000 points

[lord licorice]

Package: gnome-games
Version: 1:2.28.1-1

When I hit 100k points (or maybe it's level 10) in gnometris, the
block graphics suddenly change, but the new graphics are broken. I'm
just playing like normal and whenever it hits a certain point the
graphics change immediately after I clear a row. I'm using the Plain
theme. The new graphics have black borders around each square. There's
a screenshot here:

You can see that the block graphics are pushed off to the bottom-right
and there's a line of corrupted pixels at the bottom. The game is
still playable, and the graphics from then on are fine, but the blocks
still on the board remain weird-looking until I push the window off
the side of the screen, and then when I move it back it's refreshed
and correct again.

I'm on debian sid running XFCE
