VBO is loading and unloading chunks several times per second

Can reproduce.

Some more example screenshots.

Only happens when turning it on after joining a world, turning it on before joining a world gives me no problems. (reloading chunks by using F3 and A causes the flickering to stop).
edit: by "it" I mean VBO

Sometimes Minecraft crashes as well, no crash report, but development console says:
[16:40:22 ERROR]: Game ended with bad state (exit code 255)
[16:40:22 INFO]: Ignoring visibility rule and showing launcher due to a game crash

Still in 14w30a

it started to get really bad for me

Confirmed in 1.8-pre

Will upload screenshot and crash report in a min.

Computer specs: Windows 8.1 64-bit, Java 8 Update 11, 6GB RAM (3GB allocated to JVM)

I did notice that certain chunks would stay loaded, while others flickered
