Sometimes, respawning causes massive lag that can be solved with f3+a

Sometimes, after respawning, frames start to stutter a lot. On the F3 pie chart, under root.gameRenderer, the "level" portion quickly takes majority.

Pressing F3+A to reload chunks solves this frame stutter, but I find it rather immersion-breaking to have to press F3 and A upon respawn. Also, those without the knowledge of this workaroudn may find this buy frustrating to deal with.
