--- Comment #22 from Andreas Reis <andreas.reis at gmail.com> ---
Haven't gotten a crash for months now, so I closing as WFM.

I know compton is unrelated, but if it's of interest: Its option that causes
the corruption is glx-swap-method, eg.

backend = "glx";
glx-swap-method = "1";

man: "GLX buffer swap method we assume. Could be undefined (0), copy (1),
exchange (2), 3-6, or buffer-age (-1).  undefined is the slowest and the
safest, and the default value. […] buffer-age means auto-detect using
GLX_EXT_buffer_age"

1-6 causes full screen corruption on content changes, with 1 being worst by
far. buffer-age mostly works, but sometimes causes individual window corruption
on resize.
