It might be a driver issue. Try turning off Hardware Acceleration via SeaMonkey Preference window.

Yes, related! Switching HA off heals the problem, after switching on problem reappears (always after quit - relaunch)

I never saw that again with other versions, problem only visible with 20160205232941
