I recently ran into a "bug" on Minecraft 1.8.7 where all blocks, entities, etc will flicker between white and their original textures.

I have epilepsy, and am very thankful that I have quick reactions.

Unfortunately, I could only record at 30FPS but play games at 144FPS (because I have a 144Hz monitor) so for you it will seem slow, but for me it flickers every other frame.

Something like this:

Normal --> White --> Normal --> White --> Normal --> White --> Normal --> White --> etc
Frame1-> Frame2-> Frame3-> Frame4-> Frame5-> Frame6-> Frame7-> Frame8-> etc

It happens every time an item is picked up and flashes insanely fast.

There are no mods installed, just plain vanilla 1.8.7.
