Out of memory - Windows 8 & JRE7

Chunks will not unload. Out of memory loop.

Minecraft runs with the command: ""C:\Program Files (x86)\Java\jre7\bin\java.exe" -Xms1024M -Xmx1300M -jar Minecraft.jar"
When minecraft (Java.exe) reaches 700MB it gets out of memory.
If i resize the screen while out of memory i get an error log (See Attachment)

I DIDN'T have this problem on Windows 7.

Want to test it?

1. Run minecraft.
2. Join an server.
3. Teleport to differant chunks (Or worlds) and let them load.
4. Crash

Video demonstration (Dutch Server)
