What version? And how to reproduce that.
It was from tragic lantern. I don't remember which version. It was like, from 2-3 days before firmware 2.0.2 came out.
It happened in the field at a critical time. I was time-pressed to get a shot.
Turn it on, focused, and the live view froze with a purple image stretched/warped/interlaced looking. The camera just froze entirely, nothing works, pushing the on/off button wouldn't turn off. Pulled out the battery, put it back in. Boots up like usual. Half-press focus, camera focuses. Takes shot, purple stretched-image-interlaced screen.
Tried this like 5 times. Happens every time. Had to pop in a non-ML card. Works fine like normal.
When I got back, I looked for error logs, but nothing wrong with it. Tried booting, took a shot, works fine like normal ML. Couldn't reproduce it. Formatted the card and reinstalled ML to make sure. Haven't had that since.
Not sure what happened there.
