[Alistair Buxton]

Thanks.

==18357== 4,419,486 bytes in 245,527 blocks are definitely lost in
loss record 6,586 of 6,587

/usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so)

I have fixed this one and sent a merge request upstream, see:

This is the background pixmap. 1920*1080*4 = 8,294,400. This is
intentionally "leaked".
