CLONE - Player gets hurt while sitting in minecart and taking screenshots or minimizing / maximizing the screen

World to reproduce

I've attached a world to reproduce that issue.

Load the world, mount the minecart and press F2 and the player will get hurt 1/2 heart.

Strange thing is the inconsistency. Turning different directions can sometimes let you fire off a screenshot without taking damage.

It's not primarily the action of taking screenshots, the damage also occurs when minimizing / maximizing the screen with F11.
Maybe that's a matter of peak CPU utilisation while taking screenshots or changing the screen, so that the internal tickers won't keep up.

The directional dependancy Jon turned out may be cause by the render load - if the player looks at the dirt wall may be less to render compared with looking in the open areas.

Same here, but not taking a screenshot, just lag spikes, death from suffocating in a wall.

@Sycholic: Yes, I turn blackish, but the screenshots are not synchronizable between me and the viewer (always looking normal), so I took some screens in the 3rd-person mode.

My investigation of this bug has lead me to believe that it's the same bug as MC-100, so I'm closing it as a duplicate now. Re-open the bug report if the problem still occurs in future versions (1.4.3).

Ok, thanks. (Regular users (non-mods) cannot reopen bugs, we have to Clone instead)

Fix confirmed in 1.4.3 pre
