Weird white flashes

Looks like some problem with water texture.

This seems to be related to Mip-Mapping, if you have Mip-Mapping turned off, it'll cause some flickering.

For stability and especially security reasons, I would strongly suggest you update your Java to the latest 1.7.0_60 version http://www.java.com/en/download/.

• When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp.

no it wasn't related to Mip-Mapping, as it was at the highest setting of mip mapping. Also, I restarted minecraft and it suddenly didn't do the white flashes anymore.

Update: It actually was because of mip-mapping, but only when I had mip mapping turned off, it would stop flickering.
